Yes,
Yes.
Yes, it can.
No. An electromagnetic wave IS electric and magnetic fields.
As gamma rays are neutral it cannot be deflected by electric field.
Put a wire carrying an electric current near a compass and it causes the needle to deflect.
Yes,
Yes.
Yes, it can.
Only if 1) the metal is magnetic (Iron, Nickel, Cobalt or magnetic alloys) or 2) the metal is carrying current
Communication takes on many forms. It can be by a system of flashing lights, a movement of an indicator, or by reproducing sound.A signal light can be made using an electric lamp, an electrical source and a switch.The wire separating the lamp and the switch can be many miles and still work.In the same way, the electric current can be made to power a solenoid (electromagnet) and deflect a needle.Using fine control of an electric current, sound can be modulated onto a voltage and reproduced at the other end using a coil and diaphragm, a telephone.Electricity and magnetism form the basis of electromagnetic waves, known as radio waves. There are many different ways of modulating the signal onto a carrier wave and many different frequencies that can be selected and separated.The digital world is controlled by electricity being either 'on' or 'off', just two states, which can be manipulated very rapidly to form a code, containing masses of information.Digital information can be sent using electricity (copper cables), or light (fiber optic), or radio. DAB, DTV, WLAN, Bluetooth, etc.
A compass needle test will determine whether a current is flowing in the wire.IF the current is flowing the compass needle will deflect from alignment with the wire.
No. An electromagnetic wave IS electric and magnetic fields.
As gamma rays are neutral it cannot be deflected by electric field.
Yes. An electric current is surrounded by a magnetic field, and this will affect a compass. Please note that this is more noticeable in the case of DC - for AC, the current changes all the time, it changes very quickly, and the AVERAGE value of the magnetic field is zero.
A magnetic field would deflect both alpha and beta particles, as would a charged electric field.
Yes because tap water is a good conductor of electricity.
