Question

Induced voltage in a conductor is a function of magnetic field strength, conductor numbers and :

a) conductor cross- sectional area, b) conductor wire size, c) an external voltmeter, d) conductor speed

When a current carrying wire is located in a uniform magnetic field the direction of the current the same as that of the field.

a) there is a force on the wire tends to move it parallel to the field

b) there is a force on the wire thet tend to prevent rotatio

c) there is neither a force nor a torque on the wire

d) there is a torque on the wire that tends to keep it parallel to the field
