- 13 see photoA standard door into a house rotates about a vertical axis through one side, as defined by the door's hinges. A uniform magnetic field is parallel to the ground and perpendicular to the axis. Through what angle must the door rotate so that the magnetic flux that passes through it decreases from its maximum value to 1/4 of its maximum value? Give your answer in degrees, not radians. Number UnitsSuppose you wish to produce a 1-T magnetic field in a toroid with an iron core for which magnetic susceptibility is x = 3 x 10³. The toroid has a mean radius of 14 cm and is wound with 600 turns. Hint a. What current is required to produce this magnetic field in the iron core? Current of b. For comparison, what current is required to produce the same magnetic field in an air-filled toroid of same geometry? Current of A is needed. Submit Question A is needed for toroid with no iron core. While it is not always practical to have region of magnetic field filled with ferromagnetic materials, this dramatic increase in strength of magnetic field produced is useful in some applications you will see in upcoming chapters.
