Any coil produces a magnetic field when it has an electic current passing through it.
It's usual to use copper wire, and 1 amp through ten turns has the same effect as ten amps through one turn . . etc.
Yes, but only if the magnet or the wire are kept moving.
No. In order to induce an EMF, the coil and the magnet must be moving in relation to each other.
Electrical energy
If a wire is wrapped around a ferromagnetic material (those which are attracted by a magnet) and a current is flown through the wire, the material behaves like a magnet. This phenomenon is known as electromagnetism. The electromagnet can attract other ferromagnetic material just like any magnet. Usually a soft iron-core is used for good results. By such a phenomenon you get a temporary magnet whose magnetic property can be switched on or of by a switch! You can try this at home by wrapping a wire around an iron-nail and using a battery for current.Hope this helps:)
The magnetic field lines (the lines of force) around the magnet sweep the windings in the coil. This induces a voltage in the windings (through induction), and the voltage will try to drive current if it can. There is a bit more to this, but the essential elements are that the magentic lines of force cause voltage in the coil because there is relative motion between the field and the coil.
electric current in the coil of wire.
Moving a magnet quickly in and out of a coil of wire produces an electric current in the wire due to electromagnetic induction. This process generates a voltage in the coil, which can be harnessed to create electricity in devices like generators and transformers.
which end of a magnet will pick up an iron nail?
When a magnet is moved through the coil wire, it induces an electric current in the wire through electromagnetic induction. This current can be harnessed to generate electricity in devices like generators and alternators. The coil wire and magnet setup create a simple yet effective way to convert mechanical energy into electrical energy.
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.
By moving a magnet through a wire coil, an electric current is induced in the wire due to electromagnetic induction. This current is generated as a result of the changing magnetic field produced by the moving magnet cutting across the wire coil. This process converts mechanical energy (movement of the magnet) into electrical energy (current in the wire).
A magnet created when electric current flows through a coil of wire is called an electromagnet.
Electricity can be produced by moving a magnet through a wire coil, which induces a current in the coil. This process is known as electromagnetic induction and is the basis for how generators work to produce electricity. The moving magnetic field created by the magnet interacting with the wire coil creates an electric current to flow in the wire.
work as the current carrying coil-of wire on and acts like magnet when conductor flows
The two main types of galvanometers are moving coil galvanometers and moving magnet galvanometers. Moving coil galvanometers use a coil of wire that moves in a magnetic field, while moving magnet galvanometers use a magnet that moves in a coil of wire.
The most common way is with a magnet and a coil of wire. Have either the magnet or the coil (it doesn't matter which) fixed in place and the other one attached to a membrane that will vibrate with the sound. When a magnet moves past a coil of wire, it causes an electric current in the wire.
Yes, but only if the magnet or the wire are kept moving.
