55 number of coil per unit length

Currents in wire. Force

If direction is reversed they repel each other  from the force vector

Force coulomb derived for ampere

Magnetic field Faraday s law experiment
Through hall effect sensor.

Sensor vertical then rotate it in the vertical Line
Measure magnetic field of 1. 5. 10. 20. loops of wire test tube with 3 volts.

Make magnetic field bigger then you can overlapping them. Magnetic field due to solenoid

Result of Faraday's 10 year frustrating experiment comes jerking iron rod for the awesome discovery of electromagnetism pertaining to this experiment is the induction.  

Faraday question magnetic. Question Electricity from magnetism. Prof Mason showed class the analog galvanometer with which follows the formula below and shows that faster the iron core moves,the more the galvanometer can detect more current.

Thus introduced the rolls of wire in the inductor.
Changing magnetic field is called induction.

Figure out 4 different things about experiment produce maximum current from inductor coil
  Increased current to strengthen of magnetic field. 
  Faster speed means larger current
  Increase coils of wires
  Overlay coils of wires
  Decrease size of loop

Diagram for galvanometer

For example when showing a bigger loop, and unsurprisingly the less amperage with ammeter was detected when iron rod jerked in and out inside the bigger loop. 

Unit analysis of Tesla
Break unit B(magnetic flux) to fundamental units
Tesla is N/m/A

Variec 120ac to lower power to levitation coil b/c current flowing to show and adjust how high the metal ring can levitate

Mag coil up that magnetic field create current in ring creates a magnetic field going down

Split ring show nothing

Laminated ring up so much(due to reduced eddy current, with more efficiency)

Magnetic field Induced current light bulb show (light up with higher inductance)

Pickup coil or driving coil

Tesla's Wardenclyffe tower

The tower (400kilohertz and the higher it gets, more efficient it isequation below), very similar to inductor and modern inductive charging except the troubles are that it uses Earth as conductor(unknown electrostatic changes globally(environmental issues)) and problem how to charge people with electricity fees.

Tesla's Wardenclyffe tower

First thought the ring and coil interaction from induced current and current repelling each other.

Motional Emf explained

Overall E=vB
vBL=motion emf
Approach 180 degree opposite degrees

Useful equations derived for application of magnetic flux.

Magnetic field from angle as a function of x

Inductor differentiation
Below are a list of inductor to the right more inductance.

Formula for inductance

Phenomenon #2: experiment with tubes of conductive and nonconductive material when magnet is dropped inside

Pic of solenoid depiction

Representation of the electric field vector of a wave of circularly polarized electromagnetic solenoid presentation during radiation which is similar to this experiment except with wires.
