Challenge Problems
Push your limits with advanced challenges
A coil with 200 turns is placed in a magnetic field with a strength of 0.5 T. If the area of the coil is 0.1 m² and θ = 0 for maximum flux, calculate the maximum magnetic flux through the coil.
💡 Hint: Focus on how magnetic flux is calculated.
If the magnetic flux in a circuit decreases from 0.8 Wb to 0.4 Wb in 1 second, what is the induced emf?
💡 Hint: Apply the formula for induced emf.
