A circular coil consisting of a single loop of wire has a radius of 29.2 cm and carries a current of 26.1 A. It is placed in an external magnetic field of 0.322 T. Calculate the torque on the wire when the plane of the coil makes an angle of 58.5° with the direction of the field.

it has to be b, about 97 percent.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
