The magnetic field produced by a charge at a point is the force exerted by the charge on a moving charged particle at that point.
The magnetic field produced at any point by a moving charge q with velocity v in free space can be calculated using the equation B = (μ₀qv x r) / (4π*r^3), where B is the magnetic field, μ₀ is the permeability of free space, and r is the distance from the charge to the point where the magnetic field is being calculated. The cross product v x r indicates the direction of the magnetic field.
A negative point charge will be attracted towards a positive point charge in an electric field.
The electric field produced by a point charge is directly proportional to the charge and inversely proportional to the square of the distance from the charge. For a charged sphere, the electric field outside the sphere behaves as if all the charge is concentrated at the center, similar to a point charge. Inside the sphere, the electric field is zero.
The electric field produced by a single point charge in vacuum is a force field that surrounds the charge and exerts a force on other charged particles in the vicinity. The strength of the electric field decreases with distance from the charge and follows the inverse square law.
You can change the magnetic field produced by a current by altering the strength of the current flowing through the conductor, changing the direction of the current flow, or varying the distance between the conductor and the point where you are measuring the magnetic field.

As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.

The South Pole of the Earth's magnetic field is considered to be the magnetic south pole, where the magnetic field lines point into the Earth. This is opposite to the geographic south pole, which is the point that lies at the southernmost tip of the Earth's axis of rotation.
Electrostatic field surrounds a stationary charge. A moving charge has magnetic and electric field surrounding it. But since the mag. field at a point due to the moving charge keeps changing, there is also an induced electric field. this ind. electric field in turn induces a magnetic field. and this goes on in a cycle. (Maxwell equation)
The magnetic field is strongest at the point closest to the magnet.
The neutral point of a magnetic field is the point in space where the magnetic field intensity is zero. At this point, the magnetic forces acting on a particle will cancel each other out, resulting in no net force. This occurs in regions where magnetic field lines from opposite directions meet and cancel each other.
In a combined magnetic field, a neutral point is a place where the magnetic field is zero
A condition found in the region around a magnet or an electric current, characterized by the existence of a detectable magnetic force at every point in the region and by the existence of magnetic poles.Read more: magnetic-field
