Electromagnetic Forces Flashcards
1
Q
What determines the direction of force?
A
Direction of current affecting direction of the magnetic field.
2
Q
What is the direction of force when current in two conductors travel the same direction?
A
Attracted towards each other
3
Q
What is the direction of force when current in two conductors traveling different directions?
A
Repelled away from each other.
4
Q
What is the formula for calculating the forces acting on the conductors?
A
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)
