The Motor Effect

What is magnetism? When two pieces of iron are attracted to each other by physical means or electrical means.

The current has a positive charge in one side of the coil and it transforms to negative when it gets to the other side of the coil. This charge controls the magnetic field, making the like charges repeal and the opposite charges attract.

F. How did the magnet’s density measurement using the Archimedes’ Principle compare to the density measurement using the calculated volume? Which method might be more accurate? Why?

Conductor – conductor is an object or type of material that allows the flow of electrical current in one or more directions. The electrons move easily to the other side, away from the object

Lenz’s Law: “An induced EMF always gives rise to a current that creates a magnetic field that opposes the original change in flux ”1

for so long unexplained and although there has been a lot of progress in figuring out how magnetism works and what it’s caused by, it still isn’t completely understood. There are many theories about magnetism, but there is still much more yet to be discovered about magnetism. In the future it will probably be easily understood, but none the less intriguing.

Ohm’s Law also states that resistance is directly proportional to voltage and inversely proportional to current. This means that when resistance increases, so does voltage, but current decreases. This was corroborated in the experiment as well. This experiment clearly defined the relationship between current and voltage by applying Ohm’s Law to a series circuit. This information is crucial in a real life application as resistance can only be calculated when the values for voltage and current are known, and by understanding the relationship between these three quantities, many conclusions can be

Electromagnets can turn electrical energy into motion. Likewise the converse is true: they can turn motion into electrical energy.

Maxwell’s second equation (div B = 0) is simply replaced with the density of the magnetic charge, a term similar to that of the density of electric charge that occurs on the right hand side of the first of Maxwell’s equations (relating the divergence of the electric field to the density of the electric

Originally electricity and magnetism were thought of as two separate forces. This view changed, however, with the publication of James Clerk Maxwell's 1873Treatise on Electricity and Magnetism in which the interactions of positive and negative charges were shown to be regulated by one force. There are four main effects resulting from these interactions, all of which have been clearly demonstrated by experiments:

If a current is flowing, self-inductance tends to keep it from building up. Henry found that self-inductance is greatly affected by the configuration of the circuit, especially the coiling of the wire. He also discovered how to make non-inductive windings by folding the wire back on itself.

Ohm's law states that the current through a conductor between two points is directlyproportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance,[1] one arrives at the usual mathematical equation that describes this relationship:[2]

"In an experiment of this kind made on a motor with separately excited magnets, the following figures were obtained:
