1.1 What important fundamental principles are involved in the operation of a permanent-magnet type of instrument? 1.2 Is it desirable for an ammeter to have a high resistance or a low one? Should a voltmeter have a high resistance or a low one? Why? 1.3 If a coil carrying a current be placed in a magnetic field, what effect is noticed? Explain this effect in two ways, showing that it is based on fundamental laws of magnetic field. Of what importance is this principle?
