physics mcq class 12

A substance which can readily be made into magnet, is : 1. Cobalt (Co) 2. Brass 3. Wood 4. Paper

A substance which cannot be made into a magnet, is : 1. Iron (Fe) 2. Cobalt (Co) 3. Brass 4. Nickel (Ni)

The property of magnetism exhibited by magnetic substances has origin in the : 1. Configuration of electrons in atoms or molecules 2. Configuration of protons in atoms or molecules 3. Configuration of neutrons in atoms or molecules 4. All of these.

A true statement among the following is : 1. Every magnet has two poles N and S. 2. In a magnet, N and S poles exist together as a pair 3. Magnetic poles N and S cannot be separated i.e., isolated magnetic poles do not exist 4. All of these

The idea that magnetism of a substance originates in the microscopic constituent of the matter was first proposed by : 1. Weber 2. Ewing 3. Coulomb 4. Oersted

According to Ewing, the microscopic constituent in which the magnetism of a substance originates is a : 1. atom 2. molecule 3. compound 4. element

The S.I. Unit of magnetic pole strength is : 1. Weber 2. Ampere - metre² 3. Ampere - metre 4. Henry

The M.K.S. Unit of magnetic pole strength, is : 1. Ampere- metre 2. Weber 3. Henry 4. None of these

The ability to allow the magnetic lines of force to pass through it or to allow itself to be influenced by magnetic field, is : 1. Magnetic pole strength 2. Magnetic permeability 3. Magnetic field 4. None of these
