Law and Legislation. CIVIL RIGHTS LAWS. California led the nation in 1991 by enacting criminal sanctions for the violation of civil rights laws. The laws provide enhanced sentences for those convicted of violent or threatening behavior based on race, gender, religion, age, disabilities or sexual preference.
The fact that current carrying loops experience a net torque in a magnetic field is the principle behind the electric motor, where the electrical energy involved in establishing a current is converted into the mechanical energy of rotating a shaft.
Hence, reversing the current running though a wire will have the affect of reversing the direction of the magnetic force at a point some distance away from the wire. The affect that this has on the overall magnetic field depends on the shape of the wire.
