An electromagnet is typically stronger than a permanent magnet because it can be adjusted by changing the electric current flowing through it. Permanent magnets have a fixed magnetic strength that cannot be easily altered.

Is an electromagnet stronger than a permanent magnet?

Not necessarily. The key difference between a permanent magnet and an electromagnet is the a permanent magnet does not change whereas an electromagnet's magnetic feild can be altered by varying the current through it. This means that electromagnets are more useful because they can be turned on or off, turned up or down or be put in 'reverse'.


How can a magnet be temporarily magnetized when attached to a permanent magnet?

When a magnet is attached to a permanent magnet, it can become temporarily magnetized by aligning its magnetic domains with the strong magnetic field of the permanent magnet. This alignment causes the magnet to exhibit magnetic properties for a short period of time.


What is an advantage of using an electromagnet rather than a regular magnet?

A regular magnet, "Earth Magnet", can be very strong, the disadvantage of using them is that you cannot turn off the magnet. Electromagnet uses the electricity of a common battery and can be turned on and off, such as for switches in a circuit board.


Why would electromagnet be used in a recycling yard rather than a strong permanent magnet?

Because with an electromagnet, you can turn it off and on - you can pick things up with it then drop them again.


Why might a permanent magnet become unmagnetized if it is dropped?

Dropping a permanent magnet can cause the magnetic domains within the material to become misaligned, reducing its overall magnetic field strength. This process can demagnetize the magnet if it is subjected to a strong enough impact.

Of a ferromagnet an electromagnet a temporary magnet or a permanent magnet which is easy to create but loses its magnetism easily?

The temporary magnet becomes a magnet in a strong magnetic field, but its magnetic properties will disappear when that field is taken away. The ferromagnet and the permanent magnet are essentially the same thing. The electromagnet isn't that easy to make compared to the temporary magnet. Let's conduct an esperiment. If we take a bar magnet and pick up a paperclip with it, we can use the paperclip on the end of the magnet to pick up another paperclip. The second paperclip we are picking up only needs to touch the first paperclip; it does not have to touch the magnet itself. When the magnet is taken away, the paperclips no longer exhibit magnetic properties. They were acting as temporary magnets, and the simple and easy removal of the magnet cause them to lose their magnetism.


Which is a to make a steel rod into a magnet?

To turn a steel rod into a magnet, you can use a process called magnetization. This can be done by rubbing the rod with a strong magnet in one direction, aligning the magnetic domains within the steel. Alternatively, you can place the steel rod in a strong magnetic field, such as that produced by an electromagnet, which will also align the magnetic domains and create a permanent magnet.

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.


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.
