Solenoid Physics Simulation

This is a physics simulation that calculates and visualizes the magnetic field strength generated in the middle of a solenoid with specific values for current, core material, length, and amount of turns. 

Usage: 

- fill in the input fields with current, core material, turns, and length and read the magnetic field strength at the bottom

- the vertical grid lines are 1 meter apart 

- do not put in large amounts of turns per meter as it can crash the simulation because it is generating such a tightly wound coil over several meters is computationally expensive, if it does crash just reload the page

Definitions:

- Solenoid: coil of wire tightly wound into a spring-like shape and when a current is passed through it, a magnetic field is generated. 

- Core: material placed inside the solenoid to strengthen the magnetic field generated by the coil due to their ferromagnetic properties

- Current (A): flow of electric charge through the wire in the solenoid, measured in amperes

- Length (L): length of the solenoid along the x or horizontal axis, measured in meters

- Turns (T): number of times the wire is wound around the core per unit length, which is meters

- Magnetic Field Strength (B): measure of force exerted by a magnetic field on a moving charge or magnetic object, measured in the SI unit of tesla (T), millitesla (mT) which is 1/1,000th of a tesla, and microtesla (μT) which is 1/1,000,000th of a tesla

- Relative magnetic permeability (μr) - quantity that defines how easily a magnetic material gets magnetized when exposed to an external magnetic field, it is the ratio of material's permeability (μ) to the permeability of free space (μ₀)

Relative Permeability μr:

Vacuum: 1

Air: 1

Cobalt: 250

Nickel: 100

Soft_Iron: 200,000

Supermalloy: 100,000

Silicon_Steel: 3,000

Permalloy: 8,000

Ferrite: 300

Mumetal: 100,000

Permendur: 25,000

Mystery (Magnetite): 5

Formula:

B = μ₀ * μr * T/L * A

Where μ₀ is the magnetic constant which is 4π x 10^-7,  μr is the relative magnetic permeability of the core, T is the number of turns per L meters length, and A is the current in amperes.
