What are 3 ways to induce an electric current in a wire?
You can induce an electric current in a wire by moving a magnet near the wire, passing a current through a nearby wire, or changing the magnetic field around the wire.
How can you induce current in a wire using a permanent magnet?
By moving the wire perpendicular to the magnetic field lines created by the permanent magnet, you can induce a current in the wire through electromagnetic induction. The changing magnetic field as the wire moves induces an electric field, resulting in a current flow in the wire according to Faraday's law.
How can you induce a magnetic field in a piece of iron?
You can induce a magnetic field in a piece of iron by exposing it to a magnetic field, passing an electric current through it, or by rubbing it with a magnet.
How do you magnetise a needle?
You can magnetize a needle by rubbing it against a magnet in one direction multiple times. This process aligns the magnetic domains within the needle to create a magnetic field. Alternatively, you can use a strong electrical current to induce magnetization in the needle.
Will there be an induces electric current if the magnet remains at rest?
No, there will be no induced electric current if the magnet remains at rest relative to the conductor. Movement or a change in magnetic field is required to induce an electric current in a nearby conductor through electromagnetic induction.
What is key when using a magnet and a conductor to induce a current in the current?
Motion
Will there be a induced current if the magnet remains at rest?
No, a stationary magnet will not induce a current in a nearby conductor. Movement or change in magnetic field is required to induce an electric current in a conductor through electromagnetic induction.
What is the key using a magnet and a conductor to induce a current in the conductor?
A changing magnetic field, in the conductor, can induce a voltage (and, under the correct conditions, that in turn will result in a current). In the case of a permanent magnet, either the magnet or the conductor has to move.
What is the key when using a magnet and a conductor to induce current in a conductor?
Motion
What is a magnet pole in a simple generator?
Induce current in the generator windings.
Can a magnet stop an electric current?
A magnet cannot stop an electric current, but it can influence the flow of the current. Moving a magnet near a wire carrying an electric current can induce a voltage in the wire, which can affect the behavior of the current.

How can a magnet be used to create an electric current using the words magnetic field attract repel magnetic poles?
A magnet cannot use words to create an electric current. A moving magnet will induce electric current in adjacent conductors. This is usually described in terms of the rate that magnetic flux lines connecting the opposite poles of the magnet "cut" the conductors. The more flux lines cutting the conductors per second, the more current induced.
