Challenge Problems

Push your limits with challenges.

Question 1

A circular loop has a radius of 0.2 m and carries a current of 3 A. Apply the right-hand rule to find the direction of the magnetic field at the center.

πŸ’‘ Hint: Visualize the loop and position your hand accordingly.

Question 2

If a coil consisting of 10 turns has a current of 2 A passing through it, calculate the total magnetic field produced at its center, using B = (ΞΌβ‚€ * n * I) / (2 * R) with ΞΌβ‚€ = 4Ο€ x 10^-7.

πŸ’‘ Hint: Ensure you multiply the current by the number of turns carefully.
