In the diagram below, what do the three numbered vectors represent?

Explanation:

The right hand rule is used to find the magnetic force acting on a charged particle in the magnetic field. The magnetic force is given by :

Where

I is the current

B is the magnetic field

In this type of rule, the magnetic field, the electric current and the force are mutually perpendicular to each other.

In the given figure,

Vector 1 represent the magnetic field

Vector 2 represents the electric current

Vector 3 represents the force

b mirrors submit a iisner? e. for which optical devices does d sometimes have a positive value? o a a and b o b. a and c o c. b and d 0 d. b and cb

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
