Answer the following questions.
1. Does the electromagnet get stronger as you increase the number of coils
around the iron nail/rod?
2. Increasing the number of batteries increases the electricity. Does the
electromagnet get stronger when the electricity increased?
3. Does the type of core affect the electromagnet? How do you know?
4. What can make an electromagnet stronger?

Answer:

1.A simple electromagnet comprises a length of wire turned into a coil and connected to a battery or power supply. You can make an electromagnet stronger by doing these things: wrapping the coil around a piece of iron (such as an iron nail) adding more turns to the coil

2.The magnetic field is caused by the current flowing in the wire. The bigger the current the stronger the magnetic field and hence the stronger the electromagnet

3.The metal inside the coil magnifies the field created by it. Changing the metal core for a different metal will make the electromagnet stronger or weaker. Iron cores make for very strong fields. Steel cores make weaker fields

4.You can make an electromagnet stronger by doing these things:

wrapping the coil around a piece of iron (such as an iron nail)

adding more turns to the coil.

increasing the current flowing through the coil
