How many times KE and PE of an oscillator in one vibration become maximum?

The length of a magnet is large compared to its width and breadth. The time period of its oscillation in a vibration magnetometer is T. The magnet is cut along its length into three parts and these parts are then placed together. The time period of this combination will be
