He was the first to demonstrate a connection between electricity and magnetism.
Who is Hans Christian Ørsted?

A material whose atoms align with an external magnetic field and remain aligned when the field is removed.
What is ferromagnetic?
100
This device creates large voltages (accumulations of charge) using triboelectrics.
What is a Van De Graaf Generator?
100
Of the three types we discussed, the only type made up of more than one particle.
What is alpha radiation?
200
Charge is a fundamental property that makes charged particles feel this.
What is a force?
200
Although you might call him the "right hand" of Napoleon, he led a tragic life. Tandem Felix!
Who is Ampere?
200
Because magnets always have a north and a south end, they are called this.
What is a dipole?
200
Good in a power outage, a "Faraday Flashlight" uses human power to push a magnet through this.
What is a coil (connected to a chargeable battery)?
200
This kind of radiation may have negative health effects, given a high enough dose.
What is ionizing radiation?
300
The magnitude of the electrostatic force is proportional to this.
What is the product of the two charges?
(Also: product of total charge, or total charge)
300
Master experimenter who showed that a changing magnetic field can induce a current. Also, invented field diagrams to make up for his lack of mathematical skill.
Who is Michael Faraday?
300
Physicists have long looked for these, but none have yet been found.
What is a monopole?
300
This AC device is a type of transformer, exchanging current to achieve higher voltage.
What is a Tesla Coil?
300
Many versions of this common household device contain some radioactive material.
What is a smoke detector?
400
This is the effect of removing or adding electrons to a substance via friction.
What is the triboelectric effect?
400
Invented robotics and spark plug, among other things.
Who is Tesla?
400
According to Ampere, the strength of a magnetic field is proportional to this.
What is the magnitude of the current that produced it.
400
Leave your keys outside of the room before getting one of these, or you might find yourself which a few new medical problems.
What is an MRI?
400
These somewhat mysterious particles are passing through your body at this very moment.
What are cosmic rays?
500
In a field diagram, the strength of the electric field is given by this.
What is the density of the field lines?
500
She discovered several new radioactive elements including Polonium and Radium. She even drove an xray ambulance in WWI.
Who is Marie Curie?
500
This law is really a electromagnetic version of Newton's third law. (100 bonus points for also reciting the law flawlessly)
What is Lenz's Law?
500
Metal detectors work by using changing magnetic fields to create these little circular currents in nearby pieces of metal (which then created magnetic fields that induce current in the detector).
What are eddy currents?
500
Between living next to a nuclear power plant and a coal power plant, this will give you a high dose of radiation annually.
