Challenge Problems
Push your limits with advanced challenges
Design a problem where a bar magnet with a magnetic moment of 0.64 J/T is subjected to a magnetic field. Calculate the torque when at angles of 45 degrees and 135 degrees.
💡 Hint: Sine values will play a key role.
Create a scenario with a solenoid of unknown area but known turns and current. Give an equation that would allow a student to solve for its magnetic field strength given changes in current.
💡 Hint: Using direct relationships will be very helpful.
