Magnetic Effect of Current Key Points 2025
Candidates can check the magnetic effect of current key points below. It helps the candidates to get an overview of the topics that are important in the Magnetic Effect of Current chapter for the JEE Main 2025 exam. Check the key points below:
Magnetic Field Due to Current Carrying Conductor
A current-carrying conductor produces a magnetic field when the electric field surrounding it changes due to the motion of the electrons. The right-hand grip rule can be used to determine the direction of the magnetic field, which is formed by concentric circles surrounding the conductor.

Right-Hand Thumb Rule
The direction of the magnetic field created by a current can be determined using the right-hand thumb rule. It states the curl of your fingers indicates the direction of the magnetic field if you point your right thumb in the direction of the current.
Magnetic Fields Line
The strength and direction of the magnetic field are shown visually by magnetic field lines. The intensity of the field is shown by the density of field lines, which usually form closed loops. Visualising magnetic interactions is aided by an understanding of field lines.

Magnetic Force on a Moving Charge
When a charge moves through a magnetic field, it encounters a magnetic force. This phenomenon, which is essential to cyclotrons and particle accelerators, is controlled by the Lorentz force equation.
Electromagnetic Induction
The process by which an electromotive force (EMF) is induced in a nearby conductor by a fluctuating magnetic field is known as electromagnetic induction. This fundamental idea in electromagnetism governs the functioning of transformers, generators, and other electrical devices
