thanks guys for ur responses

yeah finally i got it ... minimal vibration and humming sound. though the strength of the magnet wasn't so strong but still it worked. i think i must increase the no. of turns of the coil along with voltage of the source for more stronger electromagnet. thanx anyways

fin i tried the way said by using true DC Supply through a battery. it did worked, the vibration was lesser as compared to AC converted to DC supply but in this case the strength was weaker. AC to DC source 12 V, 3 Amps logically 36 watts i.e at max i can draw 3 amps @ 12 V from it. DC...

yes you are right (this is what principle says) but as u take the iron piece towards the field or if you touch the piece magnetically attached their is a kinda vibration along with humming sound (just give it a try practically) in case of electromagnets but the same is not present in case of...

yes of course you can, all engineering departments are basically compositions and utilization of basic principles of physics with some advancements. u already are aware of basics and the advancement will be taught. rest depends on your interest and grasping nature...the more u show interest the...

Why does an Electromagnet Vibrate ? whenever any iron plate or steel spoon is placed near permanent magnet(not of very high strength) it gets attracted towards it and when it is removed from it it removes easily without any vibration effects. but if the same thing is performed with...

Well I have tried a different approach to make speakers. Normally speakers contain permanent magnets for producing sound using the property of electromagnetism when electric signals are passed through a coil kept in the magnetic field of Permanent Magnet. (ref: How Speakers Work frm How Stuff...

can anyone tell me what is the relationship between weight & length of material (CU & Al) depending on its gauge size?
