Why is the magnetic field a vector quantity?
Magnetism is a force. Vector notation is required to indicate magnitude and direction of a force.
What are negative vector?
Convenient notation for vectors of the same magnitude but in the opposite direction.
Is their any physical quantity having both magnitude and direction still not a vector?
I don't think so - is something has a magnitude and a direction, by definition it is a vector.
Why vector is staight not a curve?
Because a vector contains information about the direction. A direction, at any particular position is the tangent to the curve and this, by definition, must be straight.
What are vector quanity?
Any quantity for which a direction is relevant.Any quantity for which a direction is relevant.Any quantity for which a direction is relevant.Any quantity for which a direction is relevant.
Why is the magnetic field a vector quantity?

What are negative vector?
Convenient notation for vectors of the same magnitude but in the opposite direction.
How do you find the direction of a vector?
To find the direction of a vector, you can calculate the angle it makes with a reference axis, often the positive x-axis. Use trigonometry functions such as tangent or arctangent to determine this angle with respect to the chosen axis. The direction can be expressed as an angle or in unit vector notation.
Is the direction of south a vector apex?
Yes, the direction of south can be considered a vector because it has both magnitude (distance) and direction (southward). A vector is any quantity that has both of these characteristics.
Does the phrase direction of zero vector have physical significance?
No, the zero vector has no direction as it does not have magnitude or point in any specific direction. It represents a point in space with no displacement.
How can you define relation between a scalar and vector quantitry?
The (any) vector has 'direction' .
What does a vector equal?
Any other vector with with the same magnitude and the same direction.
Is there any change in the vector if there is change in angle?
Yes, changing the angle of a vector will result in a change in its direction. The magnitude of the vector remains the same, but the direction it points in will be different.
What is the difference between gradient and vector notation?
In the name of God; It must be mentioned that a vector has two important characteristics; 1- direction and 2- quantity. in other word for identification a vector these two characteristics must be defined. for example when we speak about displacement of a body it must has direction and quantity. but about gradient, it has a general mean: difference. Also a specified mean may be defined for it: "any increase or decrease in a vector or scalar field". it is a vector field.
What is the example of a free vector?
An example of a free vector is wind force as it has both magnitude and direction. This vector can be represented by an arrow pointing in the direction of the wind with a length corresponding to the strength of the wind.
