Electricity Merit Badge Requirement 3: Electromagnet
Make a simple electromagnet and use it to show magnetic attraction and repulsion.
Electricity Merit Badge Requirement 3 Helps and Answers
Making a simple electromagnet to show magnetic attraction and repulsion is not difficult. Here’s how:
Materials You Need:
- A cardboard tube (like from a roll of paper towels)
- Insulated (plastic-coated) wire
- A 4.5-volt or 6-volt battery
- A switch made from a paperclip and two thumbtacks attached to a block
- A small compass
Steps to Make the Electromagnet:
- Wrap the Wire: Take the insulated wire and wrap it around the cardboard tube.
- Connect the Battery: Attach one end of the wire to the positive (+) side of the battery and the other end to one side of the switch. Then, connect a wire from the other side of the switch to the negative (-) side of the battery.
- Place the Compass: Slide the small compass into the middle of the cardboard tube. Make sure it can move freely.
- Use the Paperclip as a Switch: Position a paperclip close to the thumbtack to make a simple switch. You can swivel the paperclip against and away from the thumbtack to open and close the electric circuit.
- Observe the Compass: Watch what happens to the compass needle as you open and close the circuit. When you close the circuit (by touching the paperclip to the thumbtack), the electric current flows through the wire, creating a magnetic field. This makes the compass needle move. When you break the circuit (move the paperclip away from the thumbtack), the magnetic field disappears, and the compass needle returns to pointing north.
Remember, be careful when working with batteries and wires, and don’t leave the battery connected for too long, as it can get hot. Have fun experimenting with your electromagnet!
Electricity Merit Badge Requirement 4: DC and AC
Explain the difference between direct current and alternating current.
Electricity Merit Badge Requirement 4 Helps and Answers
Sure, let’s break down the difference between direct current (DC) and alternating current (AC)s:
Direct Current (DC):
- DC flows steadily in one direction, like water flowing in a straight pipe.
- It’s like a battery in your flashlight, where the electric current always goes from the positive (+) end to the negative (-) end.
- DC is simple and easy to understand but may not travel long distances efficiently.
Alternating Current (AC):
- AC constantly changes direction, like a swinging pendulum.
- It’s the type of electricity that powers most of our homes and devices.
- AC changes direction many times per second (measured in Hertz, or Hz), typically 60 times per second in the U.S.
- AC is more efficient for long-distance transmission because it can be easily transformed into higher or lower voltages.
In simple terms, think of DC as a straight path for electricity, like a one-way street, while AC is like a winding road that switches directions, but it’s better for delivering electricity over long distances. Both types have their uses in different situations, but AC is more common in our daily lives.
Electricity Merit Badge Requirement 5: Battery and Bell
Make a simple drawing to show how a battery and an electric bell work
Electricity Merit Badge Requirement 5 Helps and Answers
Battery and Bell Drawing
This diagram illustrates the workings of an electric vibrating bell. Here’s a straightforward explanation:
The diagram presents an electric vibrating bell setup. To understand its functionality, let’s follow the path of the electric current:
- Pushing the button allows current to flow from terminal A to the electromagnet, labeled F.
- The current then travels to a moving contact, C, and proceeds to contact post D, finally exiting through terminal E.
Now, how does this current make the bell ring?
- As you press the button, electromagnet F attracts an iron armature, labeled B.
- This armature has two attachments: the moving contact C and a hammer, H.
- The hammer strikes a gong or bell, producing the ringing sound.
- As the armature is drawn towards the magnet, the contact C is pulled away from post D, breaking the circuit and cutting off the current.
- When the current stops, the electromagnet loses its magnetic force. A return spring, G, then pulls the armature and contact C back towards post D.
- Once contact C reestablishes connection with post D, the current flows again, and the cycle repeats. This rapid repetition creates the continuous ringing or vibrating sound.

Why a Fuse Blows or a Circuit Breaker Trips:
A fuse blows or a circuit breaker trips to protect your home’s electrical system from problems. It happens when there’s too much electricity flowing through a circuit, which can be dangerous. This can occur if there are too many devices plugged in or if there’s a short circuit (a wire touching something it shouldn’t). The fuse or breaker acts like a safety switch to stop the flow of electricity and prevent fires or damage.
Finding a Blown Fuse or Tripped Circuit Breaker:
To find a blown fuse or a tripped circuit breaker in your home, follow these steps:
- First, if the lights go out or something stops working, unplug any devices from that circuit to be safe.
- Check your home’s fuse box or circuit breaker panel. It’s usually in the basement, garage, or utility room.
- Look for a fuse that has a broken wire inside or a circuit breaker that’s in the “off” position. These are the signs of a blown fuse or tripped breaker.
Safely Resetting the Circuit Breaker:
If you have a tripped circuit breaker, you can safely reset it:
- First, unplug the devices on that circuit.
- Find the circuit breaker that’s in the “off” position.
- Push the breaker switch all the way to the “off” position and then back to the “on” position. You should hear a click.
- Now, plug your devices back in one by one to make sure everything’s working.
Remember, it’s important to be safe and not overload your circuits. If a fuse keeps blowing or a circuit breaker keeps tripping, it’s a sign of a problem, and you may need an electrician to check it out.
