One of the laws of physics is that when a conductor moves in a magnetic field a current is induced in that conductor. If you then coil that conductor you effectively end up with several conductors and you'll get more current. Incidentally, you might be better of rotating the coil between the poles of a single magnet (a horseshoe type) rather than between two magnets as you've said in your question, because the two may cancel their magnetic fields out, depending on how they are positioned, whereas one won't.AnswerIt's voltage, NOT current, that is induced into a conductor. Current , resulting from this induced voltage, will only flow providing the conductor forms a complete circuit.
The current through a resistor or for that matter any conducting medium is caused by flow of electrons. These electrons do not flow like a stream through the resistor or conductor but undergo repeated collisions with the vibrating atoms of the resistor, transferring their kinetic energy to them. This in turn increases the vibrational energy of the atoms and manifest itself as heat in the resistor/ conductor. In turn this results in reduced drift velocity of the electrons resulting in reducing the current , thus acting as a Resistor.
Yellow is the color that reflects the most amount of light, resulting in a light value.

The process is called grounding. Many devices need to be grounded, hence the U shaped pin on a devices that make contact with the ground in normal house wiring.

one condition for the above question is either conductor or magnetic field must be rotating.considering rotating field and stationary conductor,the magnetic flux will be cut up by conductor resulting in the induced emf in the conductor.
To reduce or completely get rid of pain resulting from injuries or disorders.
You should never cut a live conductor. If it's a single conductor, you may be subject to a shock hazard to earth (ground). If it's a pair of conductors, then you will be creating a short circuit and may be burnt by the resulting arc.
When that solution is evaporated completely, only salt remains
Because by definition, ionic bond is the force of attraction between positively charged cations and negatively charged anions. To form ions, atoms should be gained (resulting in anions) and lost (resulting in cations).
The term, 'overcurrent', describes either an 'overload current' or a 'short-circuit current'.An 'overload current' is a current that is higher than a circuit's 'rated current'. For example, if you have too many loads plugged into the same circuit, then the resulting current is an 'overload current'.A 'short-circuit current' is a large current resulting when a line ('hot') conductor accidentally makes contact with either a neutral conductor or an earth (ground) conductor.
