How do you magnetize metal?
You can rub a magnet with the metal in single direction for a bunch of times (the more the better), and that will magnetize it to some degree, but it's not permanent and will demagnetize if it is hit hard with something.
Magnetic lines of flux A line of flux is a line indicating the direction in which a free north pole would travel, if placed in the field at that point. Alternatively it
Correction of short sightedness To remove this defect a convex lens is used in front of eye.
In the case of orientation polarization we have material with built _in dipoles that are independent of each other, i.e. they can rotate liberally in sharp distinction with ionic p

According to de-Broglie theory, the wavelength of de-Broglie wave is given by Where h = Plank's constant, m = Mass of the particle, v = Speed of the particle, E = Energy of
APPLICATION TO BALLISTIC MISSILES: "An unpowered and unguided missile is known as ballistic missile". The path followed by ballistic missile is known as "ballistic trajectory"
why deflection magnetometer can not be worked at poles?
Boat A is travelling at 4.6 m/s. Boat B is moving away from boat A at 9.2 m/s, as shown in the figure below. The captain of boat B blows an air horn with a frequency of 550 Hz
Assumptions: Kinetic Energy=KE, Potential Energy=PE m=mass of the skateboarder=55 kg, Velocity v=1.80m/s So ,Initial Energy(KE) of the skateboarder=mv 2 /2 = 0.5* 55 * (1.8)^
