What does X and dot mean in magnetic field?

A “cross” indicates the current is going into the page, as though you were watching the fletching (feathers) of an arrow as it travels away from you. A “dot” indicates the current is coming out of the page, as though you were watching the point of an arrow as it comes toward you!

What does X and dot mean in physics?

In both these terms, cross(X) means inward direction of field while dot(.) means outward direction. These show that either the field is having inward or outward direction.

What does X in a magnetic field mean?

Remaining wire is outside the magnetic field. We know that the electric current means charges in motion hence they move with a certain velocity called drift velocity V. The magnetic force on single charge is given by. $F _{ 0 }$ = qyB .

What do the symbols dot and cross represent?

Draw circles to represent the electron shell of each atom overlapping the circles where the atoms are bonded. Add dots to represent the outer electrons of one type of atom (H). Add crosses to represent the outer electrons of the other type of atom (Cl). A bond is a dot and a cross.

What is magnetic dot?

Now these neat-looking Tool Dots can do the same thing for my DIY gear. The dots have a self-adhesive backing for fixing to a wall, cupboard door or whatever you like.

What is inward direction?

adj. 1 going or directed towards the middle of or into something. 2 situated within; inside. 3 of, relating to, or existing in the mind or spirit.

What is cross in physics?

The cross product a × b is defined as a vector c that is perpendicular (orthogonal) to both a and b, with a direction given by the right-hand rule and a magnitude equal to the area of the parallelogram that the vectors span.

What does a dot mean in physics?

So when there is a dot above the equation it means with respect to time. What does it mean if there are two on the top or one on the side? One dot on top usually means the first derivative with respect to time (that is, speed), two dots on top the second derivative with respect to time (that is, acceleration).

What is a dot and cross diagrams?

A dot and cross diagram is a diagram used to show how electrons from the outer shells of atoms are shared or transferred in a chemical bond.

Can DOT numbers be magnetic?

Magnetic USDOT number signs are a great alternative to our adhesive vinyl decals. The magnetic signs are fully compliant with Department of Transportation regulations.

What does inward and outward mean?

outward adjective (ON OUTSIDE) inside your mind and not expressed to other people: inward feelings.

What is the meaning of cross X and dot in magnetic field?

However these symbols have a meaning interms of electric and magnetic field. In both these terms, cross(X) means inward direction of field while dot(.) means outward direction. These show that either the field is having inward or outward direction.

What is the difference between cross current and Dot current?

Cross means current will flow in perpendicular dir opp to that formed by component vector envelope. Dot means current will flow in the enclosed plane. cross means that the current direction is into the plane. while a dot means out of the plane of view.

What do the symbols in the interms of current direction mean?

Interms of current direction these symbols mean nothing. However these symbols have a meaning interms of electric and magnetic field. In both these terms, cross (X) means inward direction of field while dot (.) means outward direction. These show that either the field is having inward or outward direction.

What is the difference between cross product and dot product?

The cross product is mostly used to determine the vector, which is perpendicular to the plane surface spanned by two vectors, whereas the dot product is used to find the angle between two vectors or the length of the vector.
