Custom-trained AI does the heavy lifting

Whichever exam you're preparing for, JEEnius runs on AI models custom-trained on that exam's real papers, not generic content.

Step-by-step AI solutions

See the reasoning, not just the answer. Powered by reasoning models including Fathom AI, a perfect scorer on JEE Advanced 2025.

A charged ring in a magnetic field that's switched on. Find the angular acceleration.

ANSWER

α = qB / 2m

1 Find the induced electric field

A changing B creates a circular induced field E along the ring, giving a tangential force on the charge.

2 Apply torque = Iα

The torque from that force equals the moment of inertia mR² times the angular acceleration α.

Real PYQs

Actual previous-year questions, searchable by year, subject and topic.
