Challenge Problems
Push your limits with advanced challenges
A straight wire of length 1.5 meters carries a current of 4A. Calculate the magnetic field 2m away at a right angle to the wire.
💡 Hint: Plan your variables before computing.
Derive the expressions for magnetic field due to a circular loop of current, at a point along its axis at a distance x.
💡 Hint: Break down the circular motion into small increments for analysis.
