Please answer questions 10 11 Thanks A piece of unmagnetiz

A piece of unmagnetized iron at room temperature consists of a) iron atoms with randomly oriented magnetic moments b) microscopic domains each of which has a magnetic moment In electroconvulsive therapy an electric current is passed through the brain of a severely depressed patient and, surprisingly, the patient often feels better. Somewhat similar results are obtained with the technique of Trans- Cranial Magnetic Stimulation (TCM) in which the applied potential difference is replaced by (a) a constant magnetic field (b) a time-varying magnetic tie (c) a constant electric field c) a time-varying electric field.
