Magnetic Dipole Moment | Magnetic Dipole Moment Formula Magnetic Dipole Moment :- The product of the pole strength m of the magnetic dipole (bar magnet/current carrying loop/current carrying solenoid) and the effective length 2l of the dipole is called the magnetic dipole moment (M) of the magnetic dipole. It is a vector quantity and…

Magnetic Dipole Magnetic Dipole : – Just as two charges of equal magnitude but opposite nature form an electric dipole, in the same way two magnetic poles of equal pole strength (m) located at a certain distance (effective length) form a magnetic dipole. Examples of magnetic dipole :- Bar magnet/current carrying loop/current carrying solenoid…
Properties of Magnetic Field Lines | What are Magnetic Field Lines Properties of Magnetic Field Lines | What are Magnetic Field Lines :- Just as electric field lines graphically represent the field around an electric charge, in the same way magnetic field lines are drawn to graphically represent the magnetic field around a…

Telescope Telescope :- A telescope is an optical instrument that produces large images of distant objects by providing angular magnification to enable observation of them. It works by collecting and focusing light through a combination of lenses and/or mirrors. Many objects like stars, planets, galaxies are many times bigger than our Earth, but due…
Compound Microscope Compound Microscope :- A microscope made by combining two or more lenses to magnify extremely small objects is called a compound microscope. In this, the effect (magnification) of one lens is further increased by the other lens. Structure of Compound Microscope In this, a convex lens (O) of short focal length and…
Simple Microscope Definition of Simple Microscope A simple microscope or magnifying lens is a convex lens of short focal length. Principle of Simple Microscope When an object is placed in front of a convex lens between the optical center and focus on the principal axis, a virtual, erect and magnified image of the object…
