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.
💡 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 = (μ₀ * n * I) / (2 * R) with μ₀ = 4π x 10^-7.
💡 Hint: Ensure you multiply the current by the number of turns carefully.
