Current through a solenoid: magnetic field gives a staircase graph
We were running current through a solenoid coil with an iron core, and measuring the resultant magnetic field strength. We expected a purely linear relation for the "current-field strength" ...

What was Faraday's experiment's of induction?
I'm searching about the experiments, which Faraday has done in order to discover the electromagnetic induction phenomenon. I didn't find what I need on google scholar nor google books. Can you ...

Electromagnetic Induction experiment with solenoid
The experiment is as follows
A solenoid is connected to a galvanometer and a magnetised iron rod is passed through it. (the apparatus is not ideal, and there is no zero error in the galvanometer)
I ...

Creating a temporary magnet using a simple method
Was just wondering if someone could clarify this situation:
When I take a Allen wrench and let it come in contact with an iron nail nothing happens. Not really surprising. None of the objects are ...

Investigating the relationship between a changing B field and the curl of the electric field induced
I am currently working on a 12 page lab report on Faraday's law, essentially investigating, how for different magnetic field strength through a stationary loop of wire with N number of turns, effects ...

What is the range of the validity of the Maxwell-Faraday equation?
Similar to the question about the range of the validity of Coulomb's law, I am looking for references to literature that investigates the emirical bounds of the Maxwell-Faraday equation.
However, it ...

Lab experiment: hysteresis disappears, reappears and then disappears again. How?
In my college laboratory we were assigned an experiment to measure the hysteresis curves of a certain ferromagnetic material at different temperatures. Sounds simple, right? Well, the block of Monel ...

measuring electromagnetic induction
There is a famous law which says that a potential difference is produced across a conductor when it is exposed to a varying MF. But, how do you measure it to prove? It is quite practical.
