Magnetism and Electromagnetism - Electromagnetism (Paper 2)

Question 1

what is the construction of an electromagnet?

Answer 1

a soft iron core wrapped in wire attached to a battery. when current flows through the coil of wire it becomes magnetic.

Question 2

is there force on a charged particle when it moves in a magnetic field?

Answer 2

the movement of the charged particle is a current so it produces a magnetic field. this magnetic field interacts with the permanent magnetic field to create a force. the force is perpendicular to the direction of motion and the permanent magnetic field.
