Force on a Current Carrying Conductor in Magnetic Field

Through two parallel wires A & B , 10 and 2 ampere of the currents are passed respectively in opposite direction. If the wire A is infinitely long and the length of the wire B is 2m. the force on the conductor B which is situated at 10 cm distance from A will be

• 8×10^-6 N

• 8×10^-5 N

• 4×10^-5 N

• 4×10^-5 N

A wire is parallel to the lines of the force of the magnetic field and the current flows in the wire. Then

• The wire will experience a force along the direction of the magnetic field

• The wire will not experience any force

• The wire will experience the torque
