This current sets up a magnetic field which oscillates in phase with the transmitter current. |
The source is a gyrotron, a device that accelerates electrons through a strong magnetic field to produce microwaves. |
Secondly, a moving magnet moves in relation to the earth's magnetic field, so the behaviour of the balance might be affected. |
Iron creates the magnetic field and copper wires carry away the current generated. |
Magnetohydrodynamic waves are produced by coupling forces between the magnetic field and highly conductive fluids. |
The two low magnetic field electric motors feature compensated stray fields and are each rated at 125kW for minehunting. |
