Important Topics for HC Verma Concepts of Physics Part-2 Solutions Chapter 36: Permanent Magnets
The magnet ends are named as its poles. One end is named as the South Pole and the other one is named as the North Pole. The magnets will push away if you line up the magnets whose both the poles are facing each other. This phenomenon is known as repulsion. If you line up the two magnets facing in a different direction like one in the direction of the South Pole and the other one in the North Pole then this is known as an attraction. Like poles repel each other whereas opposite poles attract each other.
A rectangular piece of an object is known as bar magnets. It is made up of steel, iron, or any other ferromagnetic composite, or ferromagnetic object, that shows permanent magnetic properties. The bar magnet has two types of poles, a north pole, and a south pole.
Terrestrial magnetism is defined as a branch of geophysics that deals with the process of the earth’s magnetic situation.
The neutral point is defined as the temperature where the thermoelectric power of two metals becomes zero and which is in the middle among the temperature of the cold terminal and similar temperature of inversion.
A device which allows electric current to pass over other points in the circuit by generating a low resistance path is known as a shunt. A shunt is a high precision resistor that is used to measure the amount of the current flowing through a circuit.
A Deflection magnetometer defined as a device used to measure the amount of the magnetic moment and polar strength of a bar magnet. This device is used to measure the pole strengths of two bar magnets.
Gauss’s Law for Magnetism
Gauss’s law for magnetism states that the magnetic field has diversity equivalent to zero, in other words, it is defined as the law of magnetism is a solenoid vector field.
