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

Yes, 90 is considered to be a good percentile in the JEE Main 2025 entrance exam. Candidates can secure admission into NITs, IITs or IISc Bangalore if they score a rank between 1,00,000 and 1,50,000 with a 90 percentile in the JEE Main exam.
Mathematics is often considered to be the most challenging subject in the JEE Main exam, but its difficulty level varies from person to person. Some students may find other subjects more challenging based upon their strengths and weaknesses.
NCERT books are very important to prepare for the JEE Main 2025 exam. The JEE Main exam follows the CBSE syllabus for 11th and 12th classes, so NCERT books are considered to be the most reliable and necessary study materials. NCERT books explain basic fundamental concepts in a simple and clear way.
To score a 99+ percentile in the JEE Main 2025 exam, candidates require more than just knowing the JEE Main syllabus, as it required consistent practice, strategic revision, time management, and the ability to solve complex problems under pressure. However, with the appropriate resources, one can achieve these requirements.
All sections namely Mathematics, Physics, and Chemistry are mandatory in the JEE Main exam, with questions covering the entire JEE Main syllabus. To be eligible for admission, candidates must achieve the minimum qualifying marks in each subject and the overall aggregate.
Candidates can study from the NCERT textbooks of class 11 and 12 Physics, Chemistry and Mathematics to cover the JEE Mains syllabus. No changes have been made to the JEE Main Syllabus 2025. NTA removed several topics of Physics, Chemistry and Mathematics last year from the JEE Main syllabus.
Candidates must keep in mind that there is no requirement of 75% marks in class 12 for appearing in the JEE Mains exam. The JEE Main eligibility criteria of minimum 75% marks in class 12 is required at the time of securing admission across NITs, IIITs and GFTIs. Candidates can apply and appear in the JEE Mains 2025 exam irrespective of their class 12 marks.
Previous year question papers are an important source for the JEE Main preparations. However, relying solely upon PYQs is not enough to fully prepare for the JEE Mains exam. Candidates must also focus on covering the entire syllabus, developing strong conceptual understanding, practising time management, and attempting mock tests.
