3:56 PM Thu 28 Apr < то (b) A solenoid, similar to that shown below, has 500 circular turns each with a radius of 45 cm. (i) This coil is placed perpendicular to a uniform magnetic field of 2 T. What is the EMF induced in the coil if the magnetic flux density is doubled in 500 ms. (5 marks) (ii) A magnet is dropped through the wire coil as shown below. As you look down the coil from above, clearly describe what direction current will flow at end X of the coil and what magnetic pole is produced at end X of the coil. (4 marks) (c) In b(ii) the magnet is initially falling with an acceleration due to gravity of 9.8m/s². Explain why the magnet will not continue to fall with that acceleration. (3 marks) 51% > >
