Different ways to induce current in a coil are as given below:
(1) If a magnetic field is changed round a coil then an induced current is set up in the coil. It can be done by taking a bar magnet and bringing it closer to the coil or taking it away from the coil.
(2) If a coil is moved in a magnetic field, then again an induced current is set up in the coil.
(3) If a coil is rotated in a uniform magnetic field, it may also cause an induced current in the coil.
(4) If we take two coils and insert them over a non conducting cylindrical roll then on changing current flowing in one coil, an induced current is obtained in the other coil.
CommentYou don't induce a 'current' into a coil; you induce a voltage. If that coil is open circuited, then no current will flow. If, on the other hand, the coil is connected to a load, or its opposite ends short-circuited, then the induced voltage will cause a current to flow. Remember, current will only flow if there is a load, or short circuit, and the value of the current will depend upon the value of the induced voltage and the resistance of the load or short circuit.

If a magnet is held close to a coil of wire will it cause current to flow?
Yes, but only if the magnet or the wire are kept moving.

How can you make a magnetic field using a coil of wire and an electric current?
To create a magnetic field using a coil of wire and an electric current, simply pass the electric current through the wire coil. The flow of electrons in the wire generates a magnetic field around the coil. The strength of the magnetic field can be increased by increasing the current or by adding more coils to the wire.
What are four ways to make an electromagnet stronger?
Increasing the number of turns in the coil of wire. Using a core material with better magnetic properties, such as iron. Increasing the current flowing through the wire. Using a thicker wire with lower resistance in the coil.
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 cylindrical coil of current carrying wire?
A cylindrical coil of current-carrying wire is a type of solenoid - a coil of wire wound in a helical shape around a cylinder. When an electric current flows through the wire, it generates a magnetic field along the axis of the cylinder. This type of coil is commonly used in electromagnets, transformers, and inductors.
What must pass through a coil in order to make an electromagnet?
An electrical current will cause an electromagnet to energise.
What has to happen around a coil of wire to generate an induced current?
pass a magnetic field through the coil of wire.
