A circular loop of radius 0.1 m carries a current of 5A. Calculate the magnetic field strength at a point 0.3 m along its axis.
💡 Hint: Be sure to substitute values for μ₀, I, and R correctly.
Two equal loops of radius 30 cm carrying a current of 2A are placed 1m apart. Calculate the resultant magnetic field at a point halfway between them.
💡 Hint: Consider how the fields from both loops interact.
