How are electromagnets diffrent to either temporary or pemanent magents?
Electromagnets are formed by passing an electric current through a coil of wire, creating a magnetic field as long as the current flows. Temporary magnets are magnets that only exhibit magnetic properties when placed in a magnetic field. Permanent magnets retain their magnetism without needing an external magnetic field or electric current.
How are electromagnets different from magnets?
You can turn electromagnets on and off.
What is the conclusion of electromagnets?
Electromagnets are temporary magnets that produce a magnetic field when an electric current flows through a coil of wire. They are widely used in various applications such as electric motors, MRI machines, and telecommunications devices.
What are the differences between electromagnets and permanent magnets, and how do electromagnets differ from permanent magnets?
Electromagnets and permanent magnets differ in how they are created and their magnetic properties. Electromagnets are temporary magnets created by passing an electric current through a coil of wire, while permanent magnets are naturally occurring magnets with a fixed magnetic field. Electromagnets can be turned on and off by controlling the electric current, while permanent magnets always have a magnetic field.
What are the other instruments or devices that use electromagnets to operate explain how they work?

How are electromagnets different from permanent magnet?
Electromagnets are temporary magnets that require an electric current to generate a magnetic field, which can be turned on and off by controlling the current flow. Permanent magnets, on the other hand, retain their magnetism without the need for an external power source. Electromagnets are versatile and can have variable strength, while permanent magnets have a fixed magnetic strength.
What are three types of magnets?
They are permanent, temporary and electromagnets
Why is a elctromagnet temporary?
An electromagnet is temporary because it only produces a magnetic field when an electric current flows through it. Once the current is turned off, the magnetic field disappears. This makes electromagnets versatile for various applications where temporary magnetic control is needed.
What are some properties of a temporary magnet?
Temporary magnets are materials that can be easily magnetized but do not retain their magnetic properties once the magnetic field is removed. They include materials like soft iron and nickel. They are commonly used in applications where a temporary magnetic field is needed, such as in electromagnets.
How are electromagnets and permanent magnets different?
Electromagnets are temporary magnets that produce a magnetic field when an electric current flows through them, while permanent magnets retain their magnetism without the need for an external electric current. Electromagnets allow for the control of the magnetic field strength by changing the current, while permanent magnets have a fixed magnetic strength.

What types of magnets are temporary?
Temporary magnets include electromagnets and soft magnets. Electromagnets are made by passing electric current through a coil of wire wrapped around a magnetic core, and their magnetism can be turned on and off by controlling the electric current. Soft magnets are materials that can be easily magnetized but lose their magnetism quickly once the external magnetic field is removed.
