1. Two parallel conductors carrying currents I1 and I2, as shown in the figure below. What is the magnitude and direction of the magnetic force experienced by both conductors? (μo = 4π. 10-7 Wb.A-1.m-1)
Known :
The electric current 1 (I1) = 3 Ampere
The electric current 2 (I2) = 5 Ampere
The permeability of free space (µo) = 4π x 10-7 wb A-1 m-1
Distance between both conductors (L) = 5 cm = 5 x 10-2 meters
Wanted: The magnitude and direction of the magnetic force
Solution :
The direction of the electric current on conductor 1 is opposite with the direction of the electric current on conductor 2. Antiparallel currents (in opposite directions) exert a repulsive force on each other.
The magnitude of the magnetic force :
F/l = 6 x 10-5 Newton

2. Two parallel wires carrying currents I1 and I2 are 20-cm apart. What is the magnitude of the magnetic force experienced by each wire (μo = 4π. 10-7 Wb.A-1.m-1)
Known :
The electric current 1 (I1) = 5 Ampere
The electric current 2 (I2) = 4 Ampere
The permeability of free space (µo) = 4π x 10-7 wb A-1 m-1
Distance between both wires (L) = 20 cm = 20 x 10-2 meters
Wanted: The magnitude of the magnetic force
Solution :
The direction of the electric current on conductor 1 is opposite with the direction of the electric current on conductor 2. Antiparallel currents (in opposite directions) exert a repulsive force on each other.
The magnitude of the magnetic force :
F/l = 2 x 10-5 Newton
