Vector.
A magnetic field is neither: it is a vector field with both direction and quantity.
When one refers to the strength of a magnetic field, they're usually referring to the scalar magnitude of the magnetic field vector, so no.
Charge is not a vector.
No,because electric field (force/charge) is a vector quantity, i.e. , it has both magnitude as well as direction.
The strength of the electric field is a scalar quantity. But it's the magnitude of thecomplete electric field vector.At any point in space, the electric field vector is the strength of the force, and thedirection in which it points, that would be felt by a tiny positive charge located there.

Yes, the magnetic field is a vector quantity because it has both magnitude and direction.
A vector is a quantity with both magnitude (strength) and direction. Like a force having a strength in pounds and a direction. Or a wind having magnitude (in mph) and direction (Northeast). A scalar has only magnitude. Like the length of a segment or amount of peanuts in a jar. Scalars are just numbers.
Electrostatic potential is a scalar quantity. It represents the potential energy per unit charge at a given point in an electric field.
Charge is not a vector.
No,because electric field (force/charge) is a vector quantity, i.e. , it has both magnitude as well as direction.
Electric field is a vector quantity, as it has both magnitude and direction. The direction of the electric field at a point is the direction of the force that a positive test charge would experience if placed at that point.
Magnetism is a force. Vector notation is required to indicate magnitude and direction of a force.
Both, E=Es + Ev = cB therefore, B= Es/c + Ev/c = Bs + Bv. The electric and magnetic fields are quaternion fields consisting of a scalar field and a vector field. Contemporary Physics has not realized this yet. Correct Relativity Theory is a manifestation of quaternion fields, consisting of a scalar field and three vector fields. This shows up in the Energy Momentum four vector, E= Es +cmV. Actually the Lorentz Force is both scalar and vector: F=qvB = - qv.B + qvxB it makes no sense consider only qvxB and to ignore qv.B.
Gravitational field is a vector quantity, as it has both magnitude (strength) and direction. It represents the force experienced by a mass placed in the field due to the presence of another mass.
A quantity that has both magnitude and direction often has an arrow drawn over the unit of measurement. This is known as a vector quantity, as opposed to a scalar quantity which has no direction.
