To solve the problem, we need to understand the relationship between the time period of a bar magnet and the magnetic field strength. The time period \( T \) of a bar magnet suspended in a magnetic field is given by the formula: \[ T = 2\pi \sqrt{\frac{I}{mB}} \] where: - \( T \) is the time period, ...
