What happens to the direction of the current when you move the magnet back and forth?
When you move the magnet back and forth near a coil of wire, it induces an alternating current in the wire. The direction of this induced current changes as the magnet moves due to Faraday's law of electromagnetic induction, which states that changing magnetic fields induce an electromotive force (emf) in a conductor.

What happens when you move a magnet back and forth inside a coil of a wire?
When you move a magnet back and forth inside a coil of wire, it induces an electric current to flow in the wire. This process is known as electromagnetic induction and is the principle behind how electric generators work. The strength of the induced current is determined by the rate of change of the magnetic field.
How does a loudspeaker use a electromagnet?
IN a loud speaker there are two magnets. one permanent magnet that always has its northpole pointing in the same direction , and one electro magnet that can change its magnetic field in direction and magnitude. IF both northpoles point into the same direciton ,the speaker cone is pushed out, if both point in opposite directions the speaker cone is pulled in. The direction and magnitude can be controlled by the current passing through the electro magnet.
How does the electrical power flow in a circuit that continually switches direction?
In a circuit that continually switches direction, the electrical power flows back and forth in a cyclical manner. This is known as alternating current (AC) flow, where the electrons move back and forth, changing direction periodically.
What kind of current makes a refrigerator run and in what direction do the charts move?
A refrigerator runs on alternating current (AC). The direction of the electric current in the charts of AC changes back and forth periodically, moving from positive to negative in a cyclical manner.
What type to electric current changes direction repeatedly?
An alternating current (AC) changes direction periodically, moving back and forth in a circuit. This is in contrast to direct current (DC) which flows in one direction. AC is commonly used in homes and businesses because it is easily transformed to different voltages for distribution.

What direction does current flown an ac circuit?
In an AC circuit, the direction of current alternates back and forth periodically. This means that the current flows in one direction for a period of time and then reverses its direction, completing one cycle. This back-and-forth movement of current is what allows electrical devices to operate consistently and efficiently.
What kind of current goes back and forth or oscillates rather than traveling in only one direction?
what current goes back and forth, or oscillates, rather than traveling in only one direction
A horseshoe magnet is moved back and forth across a piece of copper wire an electric current is detectable in the wire?
yes, it will be very small but the inductance from the magnet should stimulate a current in the wire as it will cause electrons to move.
Current that cycles back and forth rather than traveling in only one direction?
altertnating currents

When charges continually shift from flowing in one direction to flowing in the reverse direction what current is there?
When charges continually shift direction, alternating currents (AC) are present. AC involves charges oscillating back and forth in a circuit, with the direction changing periodically. This is different from direct current (DC), where charges flow consistently in one direction.
What type to electric current changes direction repeatedly?

What does frequency mean in relation to alternating current?
Alternating current (AC) continually flows in one direction then it changes direction and flows the other way. This switching back and forth creates what is called a sinusoid or sine wave. Frequency is the rate of this back and forth switching in alternating current. Frequency is measured in Hertz (Hz) which is the number times a wave switches back and forth PER SECOND or better described as CYCLES PER SECOND.
What will happen if a nail were stroke back and forth with a magnet instead of circular motion?
You are trying to align the magnetic domains in the metal. Going in one direction helps this to occur. Going back and forth will result in a net zero domain alignment.
