The magnetic field lines (the lines of force) around the magnet sweep the windings in the coil. This induces a voltage in the windings (through induction), and the voltage will try to drive current if it can. There is a bit more to this, but the essential elements are that the magentic lines of force cause voltage in the coil because there is relative motion between the field and the coil.

How are microwaves magnetic?
Inside a microwave oven,microwaves are made when electricity passes through a device called Magnetron.Magnetron uses a strong magnet. The electricity and the magnet make microwave electromagnetic.
How do you design a shaking torch light without batteries?
You need a strong magnet, a big coil of enameled copper wire, a large capacitor, and an efficient LED. And a few odds and ends. The basic design uses the magnet and coil as a generator, or dynamo. As you shake the assembly, the magnet slides up and down past the coil, generating voltage. You rectify the AC voltage and use it to charge the capacitor. You then discharge the cap through the LED to make light.
What is magnetization of iron?
the process of converting iron to a permanent magnet is called magnetization. As iron is a ferro magnetic material it is magnetized by applying strong magnetic field across it , this makes the alignment of all the magnetic dipoles present in iron in the same direction .Even after the external magnetic field is removed they retain their arrangement , thus it becomes a permanent magnet
How is the best way to unclog the main drain under a house?
Use a acid strong enough to burn through dirt but not strong enough to burn through metal adicdasy level should be around 1.5.
What are the advantages of Permanent magnet over Electromagnet?
Unlike a permanent magnet, an electromagnet can be turned on and off. One useful advantage of this: Place a metal bar inside the electromagnet, apply current through the electromagnet in one direction, and the magnetic field would move that bar one way -- reverse the current reverses the magnetic field and the bar would move the opposite way. You could use that effect and make an electronically controlled lock for a door.
What happens when a strong electric field is passed through a permanent magnet?
The electrons of the permanent magnet would align the way the electromagnetic field passed through the magnet.
Do magnets attract through liquid?
yes a strong magnet can do
What does the combination of a magnetic field and a coiled wire create strong magnet week magnet or neutral magnet?
it creates a very strong magnet A+ users
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 do speaker use electromagnet?
Sound is made by pushing air with the cone. A coil of wire is attached to the cone. The "sound"current is passed through the coil. Any current running through magnetic flux causes the coil and cone to move. The larger the magnet the louder the sound. A strong permanent magnet is used. Electromagnets are not used, however

Strong temporary magnet formed when a current is passed through a coil of wire?
This is called an electromagnet. When a current passes through a coil of wire, a magnetic field is generated around the coil. This magnetic field creates a temporary magnet that can attract or repel other magnetic materials.
Is lodestone a weak or strong magnet?
A lodestone is a naturally occurring magnet and is considered to be a strong magnet.
Can a magnet move a car?
A magnet can move a car, if the magnet is strong enough.
Which type of magnet is created from an electromagnet?
a temporary magnet can be created by an electromagnet but it can also be created by any type of strong magnet
How to demagnetize a magnet?
To demagnetize a magnet, you can expose it to high temperatures, pass an alternating current through it, or subject it to strong impacts. These methods disrupt the alignment of the magnetic domains within the magnet, causing it to lose its magnetism.
What happens when a beam of light is passed through a colloidal solution?
When a strong beam of light is passed through a colloidal solution, then scattering of light is absorbed.
