Electromagnetic Energy: Gamma rays to Radio waves
Electromagnetic wave.
Electromagnetic wave
That is called an electromagnetic wave.
An electromagnetic wave is properly called a Transverse Electro Magnetic wave, or TEM wave. It consists of an alternating magnetic wave at right angles to an alternating electric wave, with both fields being at right angles to the direction of propagation. The plane of the electric field is defined as the plane of polarization.
In classical physics, EMR is considered to be produced when charged particles are accelerated by forces acting on them. ( Source: Wikipedia) EMR stands for Electromagnetic radiation. The electromagnetic waves that compose electromagnetic radiation can be imagined as a self-propagating transverse oscillating wave of electric and magnetic fields. The two types of fields in EMR waves are always in phase with each other, and no matter how powerful, have a ratio of electric to magnetic intensity which is fixed and never varies.

Yes, both electric and magnetic fields make up electromagnetic waves. We know that electromagnetic waves (like light) have both an electric and a magnetic component. Both of these components are waves, and they move (propagate) at right angles to each other, and in phase.
The main one is that electric current, which consists of electric charges flowing along a wire, sets up a magnetic field around the wire. The field lines are circles, with the magnetic field at right-angles to the current. The magnetic field intensity at distance r from the wire is given in SI units by: H = i/(2.pi.r) The second is magnetic induction, in which a voltage is induced in a loop of wire if the total magnetic flux linking that loop changes. The voltage induced in the wire loop (in SI units) is: V = d(flux)/dt.
An Electromagnetic Wave
Yes. And no. Light is electromagnetic radiation (that's the yes part), but it has no electric charge and it isn't "magnetic" in the normal sense of being attracted to a magnet (that's the no part). The standard models for the description of light is both as a particle (photon) AND a wave (electromagnetic radiation). The electromagnetic radiation model has electric and magnetic field values at right angles to each other propagating at the speed of light in a vacuum.
A regular pentagon consists of 5 angles of 108° which are obtuse angles.
The magnetic field will have no effect on a stationary electric charge. ( this means that the magnetic field is also stationary. ) If the charge is moving , relative to the magnetic field then there might be an effect, but the size and direction of the effect will depend on the direction of the electric charge as it moves through the field. If the charge is moving parallel to the field there will be no effect on it. If the charge is moving at right angles to the field then it will experience a force that is mutually orthogonal to the field and direction of the motion. You really need diagrams to properly explain this
Electric current is produced.Nothing until it is moved at right angles{90 degrees) to the magnetic field between it's poles. The faster it moves the larger the voltage measured between the ends of the wire.
