There is no such thing as a magnetic field without the movement of charges. And the movement of charges is electricity. One of the four fundamental forces in the universe is the electromagnetic force. Not the electric or the magnetic force, but the electromagnetic force. Basically, you can't have electricity without magnetism and vice versa. That may not make electricity and magnetism similar, but they are intertwined in a most intimate way.
Compare:
- Electricity and magnetism are both described mathematically as vector fields.
- The force attributed to both, the Lorentz force, only affects charged particles.
- A moving electric field is equivalent to a magnetic field.
Contrast:
- Magnetic field lines "loop" around their poles, electric field lines start at a point charge and continue on indefinitely.
- All materials feel a magnetic field through the effect of diamagnetism. Only charged particles feel an electric field.
- There is such a thing as a point charge, but there is no such thing as a magnetic monopole.
The similarities between magnetic circuits and electric circuits are as follows:
The equation, mmf = flux x reluctance is equivalent to emf = current x resistance.
Magnetomotive force is expressed in amperes, flux is expressed in webers, reluctance is expressed in amperes per weber, and magnetic field strength* is expressed in amperes per metre. To avoid confusion with current, the 'ampere' in this context is often spoken as "ampere turn".
[*magnetic field strength is the same as magnetising force]
Somewhat.Both forces have to deal with positive and negative charges, but they function differently.
For instance, electricity happens when electrons are excited.In a metal, the electrons will pass from atom to atom, thus generating the electricity.Magnetism, however, is the force that allows ferrous metals(metals with iron)to attract or repulse, depending on like or different charges.
So all in all, electricity and magnetism are not the same, but quite similar, in fact so similar that scientists know that they are part of the same force, jointly called electromagnetism, which is one of the four fundamental forces.
Note that Rate of Change of electric field produces magnetic field. Rate of change of magnetic field produces electric field. This process can be self- sustaining, in the form of electromagnetc radiation (light, etc).

Velocity is distance over time, Acceleration is velocity with a direction.
Some people would call it 'Natural Philosophy'. My dictionary says 'a branch of science concerned with the nature and properties of matter and energy. The subject matter of physics is distinguished from chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism and the structure of atoms.'This is a controversial question with no unique answer, but here's my take on it: Physics is the study of energy. In particular, an undergraduate physics curriculum has six general subjects: 1) Mechanics 2) Electricity & Magnetism 3) Optics 4) Thermodynamics 5) Quantum Mechanics 6) Relativity
Gravity- or for some things, magnetism.
Because that's how a conductor is defined. A conductor is something that conductors electricity or "lets it go through". An insulator is something that doesn't. A semi conductor is half way between and will allow some electricity to "go through".
Because (1) It extends to arbitrarily long distances, unlike some other forces. (2) Unlike electricity and magnetism, which also extend to arbitrary distances, it is always attractive. The result is that the (tiny) contributions of lots of individual particles contribute to one great force.
the similarities Are,in Victorian times they did not have electricity and some of the toys we have doesn't have electricity
No-one "invented" electricity. It is a natural force. However many people discovered its nature and laws, and it was Michael Faraday who realised the relationships between electricity and magnetism, hence making possible the generation of electricity, and the electric motor.

There are some at the relevant link below ; hopefully you'll find some suitable to your needs .
There are a variety of common applications of physics. Some of these include mechanical design, electricity, as well as magnetism.
There are no similarities between multicultural education and Marxism.
the similarities is big and small
Any moving electrical charge - and therefore, also, any electrical current - is surrounded by a magnetic field.As to why this is so, you can either accept it as a fact, or read some advanced scientific papers; I believe the Theory of Relativity explains the relationship between electricity and magnetism, though I don't know the details myself. Einstein's paper, "On the Electrodynamics of Moving Bodies", might be a good place to start.
one of the similarities they have is that they both farm and hunt
what are difference similarities between aluminun foil and block woods
There is definitely NO similarity or similarities on Canada and Fiji culture.
They are dark
