The wire doesn't produce current at all. The current through it depends completely on everything else in the world that's electrically connected to its ends.
The main reason for produce reverse current in a diode is "MINORITY CARRIERS". For reverse bias diode i.e negative terminal connected to p side and positive to n side the electrons in p side(minority charge carriers) attracted towards the positive polarity i.e towards positive terminal. Hence the current (reverse saturation) flows.Holes also contributed the current by attracting towards negative side.
sure whatever?
A 120V power supply connected to a 30 Ohm resistor will produce 120/30 or 4 amps of current.
move it back and forth infront of a copper wire that is connected to something i dont remember.
transmitission of current produce an electric field.and it produce power

An independent source is a source that produce constant currents and voltage. Dependent sources are voltage sources that depend on a voltage somewhere else in the network.
firstly you need a battery or a cell to produce a p.d or to produce current (flow of electrons). the opp charges will always attract each other. therefore, the electrons travel through the wire from the -ve terminal of the battery to the +ve.
There is no such thing as an 'induced current'. Voltages are induced, not currents. If a voltage is self-induced into a coil, then that voltage will oppose any change in current. If a voltage is mutually-induced into a separate coil, no current will flow unless that coil is connected to a load.
they produce a current the magnetic field has to turn motion into that current. the gas coal or water pass on that current to the magnetic field.
