Science : Ch 13 – Magnetic Effects of Electric Current

Fleming’s Right-hand rule gives:

Inside the magnet, the field lines move from :

For a current in a long straight solenoid N and S-poles are created at the two ends. Among the subsequent declaration , the incorrect declaration is:

An electron moves with a speed v along positive direction of the x-axis. If a magnetic feld B acts along the positive y-direction, then the force on the electron will act along:

The magnetic feld inside a long straight solenoid carrying current is:

The nature of magnetic field line passing through the centre of current carrying circular loop is:

Direction of rotation of a coil in electric motor is intent by:

when an iron core is inserted into a current carrying solenoid

A coil of many circular turns of wire wrapped in the shape of a cylinder

To determine the direction of force experienced by a current carrying conductor placed in a uniform magnetic feld.

An electron moves with a speed v along positive direction of the x-axis. If a magnetic feld B acts along the positive y-direction, then the force on the electron will act along

Commercial electric motors do not use

The magnetic feld inside a long straight solenoid carrying current is

The law states that if the forefinger indicates the direction of the magnetic field and thumb shows the direction of motion of conductor, then the middle finger will show the direction of induced current

A device that can convert electrical energy into mechanical energy is
