1. What metals could be used to make an induced magnet.
Physics Revision- CHAPTER 7 – Electromagnetism
When a current flows through a wire, the current creates a magnetic field around the wire.
How could you change the direction of
the magnetic field?
How could you make the magnetic
field stronger?
Draw the magnetic field line around the bar magnet below, use arrows to show the direction of the field lines. : S N
