What is the difference between a magnet and an electromagnet?
A magnet is a material that produces a magnetic field naturally, while an electromagnet is created by passing an electric current through a coil of wire to generate a magnetic field.
When does a magnet induce an electric current in a wire coil?
A magnet induces an electric current in a wire coil when there is a relative motion between the magnet and the coil, which generates a changing magnetic field. This changing magnetic field induces an electromotive force, leading to the flow of an electric current in the wire coil.
What is the difference between a permanent magnet and an electromagnet?
A permanent magnet is made of material that naturally produces a magnetic field, while an electromagnet is created by passing an electric current through a coil of wire to generate a magnetic field.
What is the difference from a normal magnet to an electromagnet?
A normal magnet is a static magnet that produces a magnetic field without needing an external power source. In contrast, an electromagnet is a magnet created by passing an electric current through a coil of wire, producing a magnetic field that can be turned on and off by controlling the electric current.
What is the difference between a solenoid and an electromagnet?
A solenoid is a coil of wire that creates a magnetic field when an electric current passes through it, while an electromagnet is a type of magnet that is created by passing an electric current through a coil of wire. In essence, a solenoid is a type of electromagnet, but not all electromagnets are solenoids.
What is the difference between a magnet and an electromagnet?

What is the difference between magnet and magnetic and magnatism?
A magnet is an object that is magnetic if it displays magnetic properties. Think of it like this; If bar magnet attracts a piece of metal towards it, it is using magnetism (fluxuations in electric current) and therefore the magnet can be said to have magnetic properties.
When does a magnet induce an electric current in a wire coil?
A magnet induces an electric current in a wire coil when there is a relative motion between the magnet and the coil, which generates a changing magnetic field. This changing magnetic field induces an electromotive force, leading to the flow of an electric current in the wire coil.
Can a magnet stop an electric current?
A magnet cannot stop an electric current, but it can influence the flow of the current. Moving a magnet near a wire carrying an electric current can induce a voltage in the wire, which can affect the behavior of the current.

A permanent magnet is made of material that naturally produces a magnetic field, while an electromagnet is created by passing an electric current through a coil of wire to generate a magnetic field.

What is a magnet that is creadted from electric current through a wire?
Electro-Magnet
How does an electric current make a magnet?
the electric current is generated by the electric field. thus by the left hand rule when current is passed through a conductor a magnetic field is generated around it so that it is a similar act of a magnet. thus it seems to be a magnet.
What controls the strength of a magnet made with electric current?
The strength of a magnet(electromagnet) made by flowing electric current through a conducting coil depends on magnitude of current. . .
What is difference between magnetic circuit and electric circuit?
magnetic circit has a magnet and electri circuit has electricity
What is a magnet created when electric current flows through a coil of wire?
A magnet created when electric current flows through a coil of wire is called an electromagnet.
What is the difference between a solenoid and an electromagnet?
A solenoid is a coil of wire that creates a magnetic field when an electric current passes through it, while an electromagnet is a type of magnet that is created by passing an electric current through a coil of wire. In essence, a solenoid is a type of electromagnet, but not all electromagnets are solenoids.
