Current
Changing this induces a current.
What is magnetic flux?
The symbol for inductance is this.
What is L?
This person codified all of electromagnetism into four equations that describe electric and magnetic fields as a function of position and time.
What is James Clerk Maxwell?
This law states that time-varying magnetic fluxes generate electromotive forces (voltages).
What is Faraday's Law?
In generators, current can be used to power this, which uses a varying current to spin a rotor.
What is a motor?
Inductance is measured in this.
What is Henry's?
Maxwell's adjustment to which law states that if a changing magnetic field induces a changing electric field, then a changing electric field induces a changing magnetic field.
What is Amphere's Law?
This law states that currents induced by changing magnetic flux are directed so that the magnetic fields created by the induced current opposes the change in the magnetic flux.
What is Lenz's Law?
This is induced current in a sheet of metal for circular loops.
What is Eddy Currents?
Inductors resist a change in this.
What is a current?
Maxwell proved that in this law electric field diverges.
What is Gauss' Law?
When magnetic flux decreases, this tries to increase the flux.
What is an induced field?
Like an ammeter, this is another instrument used to measure current.
What is a Galvanometer?
Induced current creates this.
What is a force?
Maxwell proved that in this law electric fields only curl in a changing magnetic field.
What is Faraday's Law?
When there is a change in magnetic flux, the inductor induces a large current to resist it and thus there is no current through the inductor. The inductor behaves like a broken wire or this.
What is an open switch?
A magnetic rod is inside a coil of wire which is connected to an ammeter. If the rod is stationary, what is true about the current?
What is there is no induced current?
The discovery of induction led to a method for converting mechanical work into current and vice versa and thus this was created.
What is a generator?
In Maxwell's equations, there is one zero that is present, which shows up in Gauss' Magnetic Law. The zero represent the absence of something, Therefore, this particular zero means that these do not exist.
What is magnetic monopoles?
When there is no change in flux over time and thus no induced current, the inductor behaves like this with no resistance and a closed switch.
What is a straight wire?
