24 - Magnetic fields and electromagnetism

Question 1

Define magnetic flux density

Answer 1

the force acting per unit current per unit length on a wire placed at right-angles to the magnetic field

Question 2

Force on the conductor equation (at right angles)

Answer 2

F = BIL
B = magnetic flux density
I = current in the conductor
L = length of the conductor

Question 3

Force on the conductor equation (not at right angles)

Answer 3

F = BILsine
