Challenge Problems
Push your limits with challenges.
Question 1
A wire carrying a current of 10 A makes an angle of 30° with a magnetic field of strength 2 T. Calculate the magnetic force acting on the wire if its length in the field is 5 m.
💡 Hint: Remember that sin(30°) equals 0.5.
Question 2
Determine the angle at which a wire will experience no magnetic force when placed in a magnetic field.
💡 Hint: Think about how sin behaves at these angles.
