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.
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.
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.
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.

What does a vector equal?
Any other vector with with the same magnitude and the same direction.
How can you define relation between a scalar and vector quantitry?
The (any) vector has 'direction' .
Is there any change in the vector if there is change in angle?
Yes. The angle is the direction of the vector, so if the angle changes, the direction changes.
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.
How can a null vector be a vector if there is no direction?
It has magnitude 0 and a direction and obeys vector laws, so is a vector

I don't think so - is something has a magnitude and a direction, by definition it is a vector.
Any change in the velocity of an object is a?
A Vector, as it has direction and speed.
Is any quantity having a positive and negative values a vector?
No, vector, besides a value, has also a direction.
