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.

What is the key when using a magnet and a conductor to induce a current in the conductor?
Motion
What are ways to magnetize something?
Some ways to magnetize something include stroking it with a magnet in the same direction repeatedly, exposing it to a strong magnetic field, or using an electric current to induce magnetism temporarily.
How is an electromagnet like a permanent magnet?
An electromagnet is like a permanent magnet in that both can attract objects made of iron or steel. However, an electromagnet can be turned on and off by controlling the flow of electricity through it, while a permanent magnet always produces a magnetic field.
What is an advantage of using an electromagnet over a permanent magnet?
An advantage of using an electromagnet over a permanent magnet is that you can control the strength of the magnetic field by adjusting the current flowing through the coil, allowing for greater flexibility and versatility in various applications. Electromagnets can also be easily turned on and off by controlling the current flow, enabling efficient energy usage when the magnetic field is not needed.
Compare electromagnet and permanent magnets?
The difference between an electromagnet and a bar magnet is that the bar (steel) magnet is always turned on, therefore always magnetic. The electromagnet is a magnet that is powerd by a battery so you can turn it on and off.
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.

How do you strengthen a magnet?
You can strengthen a magnet by exposing it to a strong magnetic field, either by placing it near another strong magnet or using an electromagnet. You can also induce a current in the magnet by tapping it with a hammer or passing an electric current through it to realign its magnetic domains and increase its strength.

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.

How do you convert electrical energy into mechanical energy by using a motor?
By driving electricity through the motor. The electric current generates a magnetic field; this interacts with the motor's permanent magnet to create movement.

Why must you make a magnet by using batteries?
because battery supplies a direct current and to make a magnet with using the electrical method you need to supply direct current to the material {metal}which must be wounded with a coil {solenoid}.
