What is the key when using a magnet and a conductor to induce a current in the conductor?
Motion
How is an electromagnet like a permanent magnet?
No an electromagNet is created via electricity, once the electricity stops so does the magnet it can be created using a current in a wire tightly wrapped around a iron or metal rod
What is the difference between permanent and tepoary magnets?
Temporary magnets are created using an electrical field. Once the current is switched off, it is no longer magnetic. A permanent magnet on the other hand, such as the common Ferro-ceramic magnet remains magnetic all the time because it was manufactured with all of its iron particles facing the same way.
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 a temporary magnet produced using an electrical current?
An electric current produces a magnetic field.
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 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.
Can a magnet have 3 poles?
Of course . You can make such a magnet easily using a safety pin. Take a safety pin and magnetize it using a permanent magnet. Then unfold it. The ends will have same poles and at the middle you will have the other. So you can have a magnet with three poles. Verify it using compass.

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}.
What is a temporary magnet produced using an electrical current?
An electric current produces a magnetic field.
