The electric field will not be zero between two opposite charges. For opposite charges, the point of zero electric fields will lie outside the... View Article
Plasma is a conductor but not a superconductor. Superconductors are materials with zero resistance, the resistance of plasma is not zero.... View Article
Superconductors are of two types: type 1 and type 2. A type 1 superconductor has zero resistance below the critical magnetic field and critical... View Article
Type 1 superconductors are like perfect conductors with zero resistance only when it is used below the critical temperature and the critical... View Article
There are two types of superconductors: type 1 and type 2. Type 1 superconductors have zero resistance. Type 2 superconductors have zero... View Article
When a ferromagnetic substance is heated to a very high temperature it loses its magnetic property. Ferromagnetic substance becomes paramagnetic.... View Article
Friction is the force that resists the free motion of the objects on each other. The coefficient of friction is the ratio of the resistive force... View Article
In a transverse wave, the particle vibration is perpendicular to the direction of wave propagation. Whereas, in a longitudinal wave, particle... View Article
The electric field is expressed as the negative gradient of the potential. If the electric field at a point is zero then the potential at that... View Article
The electric field is a physical field that surrounds an electric charge and it exerts a force on every other charge in that field. It can be... View Article
As the frequency increases, wavelength decreases but the speed remains a constant. Therefore, the frequency of the wave does not affect the speed... View Article
Capacitors store energy in the form of electrostatic fields between the plates. Capacitors are widely used in circuits to block DC and allow AC... View Article
Capacitors are used to store charges and capacitors alone cannot increase the voltage. Capacitors are connected along with diodes to form the... View Article
Natural frequency is the frequency at which an object vibrates when it is disturbed by hitting, plucking etc. There are different factors that... View Article
Neodymium magnets can be demagnetised by heating it above the curie temperature, which is above 350 0C. It can also be demagnetised at a lower... View Article
All magnetic materials are metals but not all the metals are magnetic. Gold is not a magnetic material. Iron is a magnetic material, so any alloy... View Article
Magnets are always attracted to ferromagnetic substances like iron, cobalt, nickel and the alloys containing them (example: steel). Ferromagnetic... View Article
