with the help of simple experiment explain that electric current produces Electromagnet class 7
Answers
Answer:
Materials
Thin copper wire
Long metal nail
12-V lantern battery
9-V battery
Wire cutters
Toggle switch
Electrical tape
Paper clips
Procedure
Cut a long length of wire and attached one end to the positive output of the toggle switch.
Twist the wire at least 50 times around the nail to create a solenoid.
Once the wire has covered the nail, tape the wire to the negative terminal of the 12V battery.
Cut a short piece of wire to connect the positive terminal of the battery to the negative terminal of the toggle switch.
Electromagnetism Diagram
Turn on the switch.
Bring paper clips close to the nail. What happens? How many paper clips can you pick up?
Repeat the experiment with the 9V battery.
Repeat the experiment with the 9V and 12V batteries arranged in series (if you don’t know how to arrange batteries in series, check out this project that explains how).
Results
The current running through the circuit will cause the nail to be magnetic and attract paper clips. The 12V battery will create a stronger magnet than the 9V battery. The series circuit will create a stronger magnet than the individual batteries did
