1. What’s the difference in electromagnet and solenoid
2. State the factors on which the amount of heat produced depends
1) The main difference between a solenoid and an electromagnet is the way they function or utilized and the way they are constructed or build..
An electromagnet is a copper coiled or wound around a solid piece of metallic core that when energized becomes a magnet..
While a solenoid is very similar in construction except the core is hollow.. A hollow core where a metallic pin or plunger is positioned. The metallic plunger is mechanically coupled or linked to a mechanism that will open or close a valve, a contact point, etc.
Basically a solenoid is an electromagnet driven mechanism that will convert an electrical energy into a mechanical form
2) Heat produced by an electric current depends on the following factors
i. Electric current
ii. Resistance of the heating element
iii. Time taken to consume electricity
