Experiments Of Produce Induced EMF And Current

Experiments Of Produce Induced EMF And Current

. Relative motion of the loop and the magnet produce the induced EMF in the loop.In fact the relative motion change the magnetic flux through the loop due to which EMF is produced.  greater the rate of change of magnetic flux, larger is the induced EMF. in this experiment.

. We use a bar magnet and a call to which a sensitive Galvanometer is connected as shown in figure.When there is no relative motion between magnet and cold then Galvanometer shows no current. when the bar magnet is moved towards the call, the magnetic flux changed and current induced in the coil.

.  When the bar magnet is moved away from coal, the magnetic flux changed and current is induced in the coil in opposite direction.this experiment can also be performed by moving the coal towards our away from the magnet. in this experiment we can produce the induced current by changing the area of coal in uniform magnetic field, as.

. When the coal is being started so as the to reduce its area and EMF and hence current affairs. The induced current disappears once there'll be no modification in space. The induced current affairs when there will be no change in area when the disturb call comes to its original cellular shape thereby increasing the area, the by.

. This current last as long as the area is changing. in this experiment we can produce the induced current by rotating the call of consist area is uniform magnetic field; is chain flux. this is the basic principle of electric generator. in this experiment, two poles are placed close to each other.

. The call P is interior scissor with a battery through a switch and rheostat, while the cold as is connected only with the galvanometer. if call, or a woman Karan in, is which Zero. when the switch is off, a current produced in apps in Oppo. direction when we open or close the switch then there will be a change of, current which.

. The lock due em in. the current is all we can is all we can vary with the horse. this principle. it is possible to link the changing magnetic field with a call by using an Electromagnetic in stand of permanent.

. Magnet let the call is placed in the magnetic field of an electromagnet. both the cool and are waves and electromagnetic. the Meg flux cool coal is by current of electromagnet and an produced in the coil.
