by running electric current all through a wire a magnetic field is created
What else can I help you with?
Inductor works in direct current?
Yes, an inductor works with direct current. It is called an electromagnet. Of course, a practical electromagnet has series resistance, otherwise the current in the inductor would increase to the limit of the current/voltage source.
How does electromagnet works in transformers?
it is because of major major ang nothing just search it we do not know it
What kind of magnet is an electromagnet?
An electromagnet is a piece of iron(usually a cylinder or rectangle)wrapped around with copper wire that when electricity runs through it it works like a magnet. Also called artificial magnet.

What is a device that uses an electromagnet to measure an electric current?
A galvanometer is a device that uses an electromagnet to measure electric current. It works by converting the current passing through it into a proportional mechanical deflection of a pointer on a scale.
How does a toaster work using an electromagnet?
A toaster works using an electromagnet by converting electrical energy into magnetic energy, which connects when the toaster is turned on. The electromagnet heats up in response to the current passing through it, which then heats the metal elements inside the toaster to toast the bread slices placed in the toaster slots.
Why does a electromagnet work?
An electromagnet works by creating a magnetic field when an electric current flows through a coil of wire. This magnetic field attracts ferromagnetic materials, such as iron, causing them to be magnetized temporarily as long as the electric current is flowing.
How electromagnet works on reed switch?
When an electromagnet is turned on, it generates a magnetic field that attracts the metal reed in the reed switch, causing the switch contacts to close. When the electromagnet is turned off, the magnetic field disappears and the contacts open again. This allows the reed switch to act as a sensor or control device in various applications.
How does relay works?
Current is supplied to the electromagnet and magnitised and attract the soft iron armature. Then it closes the contact allowing the current to flow.
How does an electromagnet work and what is its function?
An electromagnet works by using electricity to create a magnetic field around a core material, such as iron. When the electricity flows through the wire wrapped around the core, it generates a magnetic field. The function of an electromagnet is to attract or repel objects that are magnetic or to convert electrical energy into mechanical energy, such as in electric motors or generators.
Which is better a permanent magnet or an electromagnet?
electromagnet
Can a electromagnet works without inductance?
Inductance is the result of energy being stored in a magnetic field. You can't have a magnetic field without inductance.
