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.
The magnetic field from a such current-carrying wire actually wraps around the wire in circular loops, decreasing in magnitude with increasing distance from the wire. To find the direction of the field, you can use your right hand.If you curl your fingers, and point your thumb in the direction of the current, your fingers will point in the direction of the field. The magnitude of the field at a distance r from a wire carrying a current I is given by:Currents running through wires of different shapes produce different magnetic fields.Consider a circular loop with a current traveling in a counter-clockwise direction around it (as viewed from the top).lectric fields come from charges. So do magnetic fields, but from moving charges, or currents, which are simply a whole bunch of moving charges. In a permanent magnet, the magnetic field comes from the motion of the electrons inside the material, or, more precisely, from something called the electron spin.
