# NCERT Solutions for Class 10 Science Chapter 13- Magnetic Effects of Electric Current The primary focus of the subject is on the electric current's magnetic effect. Science chapter 13 Magnetic effect of electric current provides knowledge on magnets and magnetism. A magnet is a material that attracts iron-like materials. As an electric current flows through a wire, it acts like a magnet. This chapter also talks about some fundamental topics like electromagnetism, magnetic field, and the difference between magnetic and electric field

The magnetic field of a straight current-carrying conductor can be found using the right-hand thumb rule or by Maxwell's screw rule. Science chapter 13 Magnetic effect of electric current also deals with the magnetic field due to current through a straight wire, current through circular loop and force on the current-carrying conductor. Within the solenoid, the field lines are in the shape of parallel straight lines. This means that the field within the solenoid is uniform.

Science chapter 13 Magnetic effect of electric current also gives knowledge about electromagnet, electromagnetic Induction, Induced potential difference, Induced current, Fleming's Right Hand Rule. Electromagnets are magnets that are generated by creating a magnetic field within a solenoid. It's a temporary magnet that can be quickly demagnetized by interrupting the flow of current through the coil.

Flemings left-hand rule is used to find the direction of motion. A rotating device that converts electrical energy to mechanical energy is known as an electric motor. The theory behind an electric motor is that when a current-carrying rectangular coil is positioned perpendicular to the magnetic field, it experiences a force that causes it to rotate continuously.

A potential difference is produced in a conductor (coil) when it is put in a changing magnetic field, resulting in an induced electric current in the circuit. Electromagnetic induction is the term for this phenomenon. Flemings right-hand rule is used to find the direction of induced current.

In addition, the chapter discusses electric generator and domestic circuits.
