A toroid made of CRGO has an inner diameter of 10 cm and an outer diameter of 14 cm. The thickness of the toroid is 2 cm. 200 turns of copper wire is wound on the core. μo = 4π × 10⁻⁷ H/m and μr of CRGO is 3000. When a current of 5 mA flows through the winding, the flux density in the core in millitesla is ________

The figure below shows an electrically conductive bar of square cross-section resting on a plane surface. The bar of mass of 1 kg has a depth of 0.5 m along the y direction. The coefficient of friction between the bar and the surface is 0.1. Assume the acceleration due to gravity to be 10 m/s². The system faces a uniform flux density B = −1 ẑ T. At time t = 0, a current of 10 A is switched onto the bar and is maintained.



When the bar has moved by 1 m, its speed in metre per second is ____ (rounded off to one decimal place).
