You can feel the heat waves from small electric heater on your hands and face even though the heater is on the other side of the room this is an example of

yup its correct its: c) b b

where are the vectors ?

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
