Electromagnetic Induction

What is that instrument which can detect the presence of electric current in a circuit ?

Fleming's _____ hand rule gives the direction of induced current.

Which one of the following is used in the working of an AC generator?

Which of the following situation does the current will be induced.

Observe the following diagram and state whether the given statement is true or false:

The rule used to determine the direction of current produced in the given instrument is Fleming's Right Hand Rule.

It states to stretch the thumb, the index finger and the middle finger such that they are mutually perpendicular to each other. If thumb indicates the direction of the magnetic field, the index finger indicates the direction of motion of the conductor then the middle finger shows the direction of the induced current.

Observe the figure below.

Select the correct statements related to the current induced in the coil.

Find the odd one out from the box given below.

[Voltmeter, Ammeter, Thermometer, Galvanometer]

Identify the way to induce a current in a coil.

The rectangular coil of copper wires is rotated in a magnetic field. The direction of induced current change once in each_________.

Compass needle experiences a force in _____ field of a bar magnet due to which it deflects. 

The AC generator is more  _____ than DC generator.

An electrical cell is a device that is used to generate _____.

The magnet attracts small pieces of _________.

The magnetic poles always exist in _____.

The essential difference between an AC generator and a DC generator is that_____________________.

The device used for producing electric current is called a ________.

The strength of an electromagnet can be increased by _____.

Electromagnets is usually an insulated wire wounded around an iron bar.

Electromagnets create magnetic field by means of electric current.

Two coils $\mathrm{P}$ and $\mathrm{S}$ are wound over the same iron core. Coil $\mathrm{P}$ is connected to battery and key and the coil $\mathrm{S}$ is connected to galvanometer. Write your observation when:

Current continues to flow in the coil $\mathrm{P}$.
