Electromagnetic Forces

Question 1

What determines the direction of force?

Answer 1

Direction of current affecting direction of the magnetic field.

Question 2

What is the direction of force when current in two conductors travel the same direction?

Answer 2

Attracted towards each other

Question 3

What is the direction of force when current in two conductors traveling different directions?

Answer 3

Repelled away from each other.

Question 4

What is the formula for calculating the forces acting on the conductors?

Answer 4

F = Force between two conductors (Newtons pre metre length)

I₁ = Current in conductor 1

I₂ = Current in conductor 2

d = Distance between two conductors (metres)
