The magnetic field dies.
One advantage of using electromagnets is that their magnetic field can be easily controlled by varying the electric current, offering more flexibility and versatility in applications.
can be easily turned on and off by controlling the electric current, allowing for precise control and application in a wide range of devices and applications.
Electromagnets' magnetism can be manipulated. Electromagnets can be magnetised and demagnetised by passing electric current. Therefore they are used in motors- which works when the coil is magnetised by passing an electric current. It is also used for cranes.
You can turn electromagnets on and off.
A magnet that can be turned on and off is called an electromagnet. It works by running an electric current through a wire coil to generate a magnetic field, which can be controlled by turning the current on or off.
Electromagnet which uses electric current can be turned on and off.
True.. Yes, they operate by turning the current on and off

because they can be turned on and off by opening and closing electric circuit.

Yes, they are an efficient way of sorting and transferring metals.
Electromagnets can be turned on and off by controlling the flow of electricity, while permanent magnets have a fixed magnetic field. This makes electromagnets more versatile and suitable for a wider range of applications. Additionally, electromagnets can produce a stronger magnetic field than most permanent magnets.
This is what makes a magnet an electromagnet - the ability to turn it on and off... Anyway, electromagnets can be turned off with either the help of a switch, or just by disconnecting the power supply.
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.
