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.
Even the magnetic field produced by a current-carrying wire must form complete loops. Above, you were told that a loop of current-carrying wire produces a magnetic field along the axis of the wire. The right-hand rule gives the direction of the field inside the loop of wire. The magnetic field turns back the other way outside of the loop. As shown in the figure on the right, this magnetic field from a loop of current-carrying wire looks similar to the field from a permanent bar magnet.
