Hello Everyone...
I decide to make automatic cradle for baby's, for that i use magnet attraction and repulsion property. for that i attech 2 powerful magnet on movable pipe of cradle and put one coil near this magnet.
Now to obtain movement we need to energy's coil such a way that moment of cradle can be obtain.
for that i directly connect two terminal of coil with 12V DC power supply and make switching with hand. Current Rating was 2.5A when turn on. This way i obtain movement in one direction. as i increase coil voltage large movement can be obtain.
after that i decide to switching it with micro-controller so i can obtain movement in both direction by changing current flow direction. for that i use H-BRIDGE concept.
i make h-bridge using Relay but it make noise as TICK TACK.
To Avoid this problem i use power mosfet 55NF06.
Circuit diagram is attached with this post...

Problem with mosfet is, after starting circuit mosfet start heating and after minute it become fry.
please help me, what should i do to avoid this kind of problem....?
Thank you..!!
