What does magnetic field mean in science?
magnetic field, a vector field in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable.
Which method is applied to magnetic field?
Magnetic field can be produced by any of the following methods: (i) Any magnet-bar magnet, horse-shoe magnet or round magnet can be used. (ii) A wire carrying current produces a field around it. (iii) A loop or solenoid carrying current.
What is a magnetic field in simple terms?
The definition of a magnetic field is a place in space near a magnet or an electric current where a physical field is created from a moving electric charge that creates force on another moving electric charge. An example of a magnetic field is the Earth’s magnetic field.
What is magnetic field and field line?
Glossary. magnetic field: the representation of magnetic forces B-field: another term for magnetic field magnetic field lines: the pictorial representation of the strength and the direction of a magnetic field direction of magnetic field lines: the direction that the north end of a compass needle points.
What is magnetic field Class 12?
Magnetic Field: Magnetic Field is defined as the space around a magnet (or a current-carrying conductor) in which its magnetic effect can be experienced. A magnetic field in a region is said to be uniform if the magnitude of its strength and direction is the same at all the points in that region.
When a magnetic field is applied on a stationary electron it?
Regardless of the external field’s orientation, there will always be attraction force to both external magnetic poles, cancelling each other so the net force on the electron will always be zero, causing the electron to remain stationary.
Which of the following method is applied to produce magnetic field lines?
By using a permanent magnet we can produce the magnetic field and it can be visualized by spreading iron fillings on a white paper and keeping a magnet beneath the paper. A current-carrying straight conductor produces the magnetic field.
What is meant by magnetic field in physics?
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. Magnetic fields and electric fields are interrelated and are both components of the electromagnetic force, one of the four fundamental forces of nature.
What is magnetic field example?
Examples of magnetic force is a compass, a motor, the magnets that hold stuff on the refrigerator, train tracks, and new roller coasters. All moving charges give rise to a magnetic field and the charges that move through its regions, experience a force.
What is magnetic field field?
What are magnetic field lines Class 10th definition?
Magnetic Field lines are imaginary lines along which North Magnetic Pole would move. In a bar magnet, the magnetic field lines look like. These are lines which shows direction of Magnetic Force and its strength. These are curved lines which start from North Pole of Magnet and Moves Towards South Pole.
What is magnetic field definition class 10?
The space or region around a magnet within which its influence can be felt by another magnet is called magnetic field. A magnetic field is represented by a series of lines around a magnet. The path along which north pole moves in a magnetic field is called magnetic lines of force or magnetic field line.
Which is the correct definition of a magnetic field?
Magnetic field. Written By: Magnetic field, a vector field in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable.
How is a magnetic field related to a moving charge?
Magnetic field: 1) A moving charge or current creates a magnetic field in the surrounding space (in addition to E). 2) The magnetic field exerts a force F m on any other moving charge or current present in that field. – The magnetic field is a vector field vector quantity associated with each point in space.
What are the selection rules for applied magnetic field?
Here β I is the nuclear magneton, H is the applied magnetic field, and M is the orientation quantum number. The selection rules are Δ M = 0 or ± 1 depending on whether the magnetic field is applied parallel or perpendicular to the electric radiation vector. Analysis of the Zeeman splittings provides values of the molecular rotational g -factors.
What kind of force does a magnetic field exert?
Magnetic field: 1) A moving charge or current creates a magnetic field in the surrounding space (in addition to E). 2) The magnetic field exerts a force F m on any other moving charge or current present in that field.
