    Answer~~ Lenz’s law states that induced electromotive force with different polarities induces a current whose magnetic field opposes the change in magnetic flux through the loop in order to ensure that original flux is maintained through the loop when current flows in it. Regards.

    No dear, electrostatic force is that force when static means rest charge apply force on the other charge . Magnetic force is a force when charge apply force in other charge in motion . magnetic force is also known as lorentz force. When electric force and magnetic force come together then lorentz force occur.

    The law. Coulomb's law states that: The magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them. The force is along the straight line joining them.

    (a) when theta is 90° then particle moves in a circle in a plane perpendicular to magnetic field. (b) when it enters obliquely then it moves straight due to component of velocity along magnetic field and performs cicular motion simultaneously due to component of velocity perpendicular to magnetic field. Hence the overall motion is hellix(moving forward while rotating in a circle).

    Yes, magnetic fields are dependent on the frame of reference from which you measure them. ... Well, the same charges that we saw sitting still before are now moving towards us, and hence we measure an electric current flowing in the wire, which creates a magnetic field according to Ampere's Law....

    As F = q(v x B),velocity depends on frame of reference. Hence The magnetic force is frame dependent. So, yes the magnetic force differ from inertial frame to frame.
    The net acceleration which a rising from this is however, frame independent for inertial frames (non-relativistic physics).

    The net electric charge of a conductor resides entirely on its surface. (The mutual repulsion of like charges from Coulomb's Law demands that the charges be as far apart as possible, hence on the surface of the conductor.) The electric field inside the conductor is zero. When an electric field E is applied to a conductor, free charges inside the conductor move until the field is perpendicular to the surface. ... The free charge has been brought to the conductor's surface, leaving electrostatic forces in equilibrium. A conductor placed in an electric field will be polarized.

    The principle of a potentiometer is that the potential dropped across a segment of a wire of uniform cross-section carrying a constant current is directly proportional to its length. The potentiometer is a simple device used to measure the electrical potentials (or compare the e.m.f of a cell).

    A light emitting diode is simply a forward biased p-n junction which emits spontaneous light radiation. When forward  bias is applied, the electron and holes at the junction recombine and energy released is emitted in the form of light. For visible radiation phosphorus doped GaAs is commonly used.  The advantages of LEDs are:  (i) Low operational voltage and less power.  (ii) Fast action with no warm up time.  (iii) Emitted light is nearly monochromatic radiation.  (iv) They have long life.

    • A transformer is a device that changes voltage  from one value to another.
    • Power at the input end  is equal to the power at the output end.

    Curie point, also called Curie Temperature, temperature at which certain magnetic materials undergo a sharp change in their magnetic properties. ... In the case of rocks and minerals, remanent magnetism appears below the Curie point—about 570 °C (1,060 °F) for the common magnetic mineral magnetite. In a paramagnetic material, the magnetization of the material is directly proportional to an applied magnetic field. However, if the material is heated, this proportionality is reduced: for a fixed value of the field, the magnetization is inversely proportional to temperature.
