Describe the force exerted on a conductor due to the interaction between an external magnetic field and an induced current within that conductor.

• When an induced current is created in a conductive loop, the already-present magnetic field will exert a magnetic force on the moving charge carriers within the loop. Relevant equation:
• When current is induced in a conducting loop, magnetic forces are only exerted on the segments of the loop that are within the external magnetic field. These magnetic forces may cause translational or rotational acceleration.
• The force on a conducting loop is proportional to the induced current in the loop, which depends on the rate of change of magnetic flux, the resistance of the loop, and the velocity of the loop.
• Newton’s second law can be applied to a conducting loop moving in a magnetic field as it experiences an induced emf . TOPIC 13.3 Induced Currents and Magnetic Forces
