With these solutions, you will be prepared to solve any kinds of questions related to this chapter. We are determined towards explaining all the essential concepts in the easiest way possible.

## Important concepts of NCERT Class 10 Science Solutions Chapter 13: Magnetic Effects Of Electric Current

The name of the chapter explains what we will study in the chapter. The chapter holds exciting topics and concepts that are not only important to study book-wise but also practically.

Magnetic field and field lines

• In this concept, we study the like poles of a magnet repel however unlike poles attract each other. The concept is made clear by the diagrammatic presentation of iron filings and a bar magnet.

Magnetic field due to a current-carrying conductor

• An electric current, when passed through a metallic conductor, produces a magnetic field around it.
• The concept is explained practically through an activity- a simple electric circuit in which a straight copper wire is placed parallel to and over a compass needle.
• The deflection in the needle becomes the opposite when the current is reversed
• Magnetic field due to a current through a straight conductor, circular loop, and a solenoid.
• The right-hand thumb rule

Force on a current-carrying conductor in a magnetic field

• According to a French scientist, a produced magnetic field also exerts a force on the magnet placed in the vicinity of the conductor.
• The whole concept can be easy to understand following the activity a current-carrying rod experiences a force perpendicular to its length and the magnetic field.

Electric motor

• An electric motor is a device that converts electrical energy into mechanical energy.
• The proper functioning of an electric motor is displayed with the help of a simple electric motor diagram.

Electromagnetic induction

• Electromagnetic induction explains how force is released in a magnetic field and the force causes the conductor to move.
• The force is explained moving a magnet towards a coil sets up a current in the coil circuit as indicated by the deflection in the galvanometer needle.
• Fleming’s right-hand rule labelled diagram is easier to understand.

Electric generator

• The concept is based on the phenomenon of electromagnetic induction
• A diagram has been shown illustrating the principle of the electric generator.

Domestic electric circuits

• How we receive the supply of electric power in our homes through the main supply.
• The explanation of a schematic diagram of one of the common domestic circuits.

### Exercise Discussion of NCERT Class 10 Science Solutions Chapter 13: Magnetic Effects Of Electric Current

• The exercise of the chapter magnetic effects of electric current has a total number of 32 questions.
• The first part of multiple-choice questions has 12 questions in all and are based on basic concepts of the chapter like magnetic lines of the field, electric conductor, induction, etc.
• The short answer question section also consists of 12 questions overall. These questions are to be answered with an explanation. They include topics such as what right-hand thumb rule and left-hand rule.
• The long questions are 7 in all. These questions require long explanations. This section contains typical questions like drawing a labelled circuit diagram of an electric motor and explains its working in detail.
