## Units and Dimensions in Physics Continued

Units and Dimensions in Physics Continued Dimensions: The unit of any derived quantity depends upon one or more fundamental units. This dependence can be expressed with the help of dimensions of that derived quantity. In other words, the dimensions of a physical quantity show its until its related to the fundamental units. To express dimensions, each fundamental unit is represented by a capital letter. Thus, the unit of length is denoted by L, unit of mass by M, unit of time [...]

## Newton’s Laws of Motion

Newton's Laws of Motion in Physics Newton’s experimental observations and conclusions are divided in three parts – Newton’s First Law of Motion: it states that every body continues to be in state of rest or of uniform motion along a straight line unless it is compelled to change that state by an applied force. Newton’s Second Law of Motion: It states that the rate of change of momentum of a body is proportional to the impressed force and acts in the direction [...]

## Magnetism Moving Coil Galvanometer

Magnetism Moving Coil Galvanometer Torque on a current carrying loop suspended freely in a magnetic field. When a loop is suspended freely in a magnetic field and a current is passed through it, we find that the resultant force on the loop is zero but the resultant torque is not zero. Suppose, at any instant during the rotation of the loop normal drawn on the plane of loop or axis of the loop makes an angle θ with the direction of magnetic [...]

## Magnetism in Physics

Magnetism A magnet is an object that produces a magnetic field. This magnetic field is responsible for attracting ferromagnetic materials such as iron and attracts or repels other magnets. Magnets are of two types: Natural Magnets and Artificial Magnets Natural Magnets are those magnets which are naturally found in mines. Due to their odd shape and weak attracting power, natural magnets are rarely used. Artificial Magnets are those magnets which are artificially prepared. These magnets exist in various shapes and sizes like [...]
