a magnetically soft material can be a magnetically "charged" by exposing it to a very large electromagnetic field (around 600 volts and various currents according to 'how it works') In another definition, a small current can be used to temporarily magnetise a magnetically soft material (iron, nickel or cobalt) some magnetism may remain in the object after current is removed, too.

∙ 14y agoTake a transformer which has been considered inoperative. Dismantle and take off thin wire out of it. It will be an insulated one. Now wind this over an iron nail with many number of turns say some 50 or 100. Then pass current through this using a cell. As you take pins near by the nail those will be attracted by the nail as the nail gets magnetised because of current flow. Often as we do this, soon the nail will become a magnet permanently

How can a magnet be used to create an electric current using the words magnetic field attract repel magnetic poles?
A magnet cannot use words to create an electric current. A moving magnet will induce electric current in adjacent conductors. This is usually described in terms of the rate that magnetic flux lines connecting the opposite poles of the magnet "cut" the conductors. The more flux lines cutting the conductors per second, the more current induced.
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.
Can you make a magnet without using a magnetic material Explain?
If you are referring to a magnet as an object that possesses a permanent magnetic field, then yes. There are three circumstances where magnetic fields exist, but not as a result of a permanent magnet. 1. Electric current causes a magnetic field. Thus, any wire carrying a current or even a current without a wire (like a lightning bolt) will be surrounded by a magnetic field. Since electric current is made up of moving electric charges, it is actually true than any moving electric charge creates a magnetic field. 2. It is difficult to observe outside of a scientific laboratory, but when there is an electric field that is varying in time, that creates a magnetic field. Though not easy to demonstrate directly, this turns out the physical phenomena the allows the creation of elecrtromagnetic waves, e.g. like the light we see with our eyes. 3. Thirdly, one can cause materials that are not able to work as permanent magnets to act as temporary magnets. This is the basis for electromagnets. A steel or iron core with an electric current running through a coil surrounding the core will produce a magnetic field. If you simply cut off the power source, the electric current will no longer flow through the coil. No electric current, no magnetic field. When a non-permanent magnet is created, the magnetic field it produces is just the same as the magnetic field of a permanent magnet, until the source is removed and the field disappears. All of these matters together are an essential part of the basics of electromagnetism which describes how and why the phenomena work.
Will magnets lose it's power by rubbing?
You can destroy the magnetism of a magnet by hammering ,heating or using a alternating current method.
Does electricity flow through iron?
Electromagnets are magnets that are powered by electric currents. An electromagnet is usually more powerful than a permanent magnet that does not use electricity because the strength of an electromagnet can be increased by adding additional material, such as more wire or a bigger core, and the magnetic field can be concentrated using wire coils around the core. i hope this did help
What is a magnet created using electric current?
An electromagnet. Unlike other magnets it can be switched on and off.
What is a temporary magnet produced using an electrical current?
An electric current produces a magnetic field.
How can you start and stop electric circuit?
Using a switch device which starts and stops the electric current around the circuit
Can you make electricity using a wire and a magnet?
An electric current is created when a magnet is spun rapidly inside a coil of wire. A turbine (usually powered by water or wind) spins a magnet inside a coil. This action induces an electric current in the coil that can be used to power a light bulb. Hope This Helped!! :D

Can we make magnet without using magnetic material?
Yes. Electromagnets don't require a magnetic material; they just require a conductor and an electric current.
What is key when using a magnet and a conductor to induce a current in the current?
Motion
How is an electromagnet like a permanent magnet?
No an electromagNet is created via electricity, once the electricity stops so does the magnet it can be created using a current in a wire tightly wrapped around a iron or metal rod
Why is it in lifting a metal bucket using crane there is a electrical current exist?
For this to happen, presumably the bucket, or some surrounding object, has some magnetism. If you move a magnet through an electric field, a current will be induced.
Is an electric kettle a temporary magnet?
A kettle does not have a magnetic force on its own. However, since it is metal, it can attract a magnet.
