inductor have property it oppose the change in current .
V=L di/dt
V=VOLTAGE GENERATE
L=INDUCTANCE
di/dt= change in current
suddenly when we switch off the realy , suddenly flow of current stop ,so opposite voltage generate and this will damage the component ,so remove this problem we use Free wheel diode ,it bypass the currnet .
