So E=vB and {E}={v}cross{B} but if I have for instance v=5j and B=-1k, then E is in the positive i direction. Shouldn't it be in the negative direction? Thanks.

rocketnukem said:Yes, F=qvXb or F=qvbsin(thata). Try using the right hand rule.
1.) point hand in the direction of v
2.) curl fingers in the direction of B
3.) thumb points in the direction of the force
An electric field vector is a mathematical vector that represents the strength and direction of the electric field at any given point in space. It is denoted by the symbol E and is measured in units of volts per meter (V/m).
Electric field is created by electric charges. A positive charge will create an electric field that points away from it, while a negative charge will create an electric field that points towards it. The strength of the electric field is directly proportional to the magnitude of the charge.
Electric field and velocity are not directly related. However, the electric field can exert a force on a charged particle, causing it to accelerate and change its velocity.
A magnetic field vector is a mathematical vector that represents the strength and direction of the magnetic field at any given point in space. It is denoted by the symbol B and is measured in units of tesla (T).
Magnetic fields can interact with electric fields through a phenomenon known as electromagnetic induction. When a changing magnetic field passes through a conductor, it induces an electric field, which in turn can induce a current in the conductor.
