ELECTROMAGNETISM

Action 1:

Take a straight piece of wire and curve it as a solitary circle. Presently go it through cardboard having two openings. Interface the finishes of the circle to a battery with the goal an ongoing beginnings moving through it. Presently sprinkle a few iron filings on the cardboard. Note the example of the iron filings shaped on the cardboard. Do the attractive field lines between the two pieces of the circle look like that of the bar magnet?

Action 2:

Take a rectangular circle of wire and interface its two finishes with a galvanometer. Presently hold the wire fixed or move it lined up with the attractive field of areas of strength for a molded magnet. The galvanometer shows no avoidance and consequently, there is no current. Presently move the wire descending through the field, the current is prompted in one bearing as shown by the diversion of the galvanometer (a). Presently move the wire up through the field, and the current is actuated the other way (b).

Action 3:

Shows one of Faraday's trials in which current is prompted by moving a magnet into the solenoid or out of the solenoid. At the point when the magnet is fixed, no current is prompted. At the point when the magnet is moved towards the solenoid, the needle of the galvanometer redirects towards the right, demonstrating that a current is being prompted in the solenoid (a). At the point when the magnet is pulled away from the solenoid, the galvanometer redirects towards the left, showing that the actuated current in the solenoid is the other way (b).

Action 4:

                                 

On the off chance that we bring a north pole of a bar magnet close to a solenoid, an e.m.f. Will be prompted in the solenoid by electromagnetic enlistment (a). The heading of the prompted current in the solenoid by the actuated e.m.f. Will be to such an extent that it will repulse the north pole of the magnet. This is just conceivable on the off chance that the right finish of the solenoid turns into a north pole. Thus, as per the right-hand grasp rule, the course of the actuated current in the solenoid will be clockwise. Also, when we move the north pole of the magnet away from the solenoid, the heading of the actuated current will be anticlockwise (b). For this situation, the left finish of the solenoid turns out to be the south pole.
