how does the electric field and magnetic field travel in a vacuum with respect to the direction of the wave motion?​

Answer:

An electric field is produced by a charged particle. A force is exerted by this electric field on other charged particles. Positive charges accelerate in the direction of the field and negative charges accelerate in a direction opposite to the direction of the field.

Explanation:

Since electromagnetic waves have an electric and magnetic vector. An electric and magnetic field has no need for a medium to show their effect. Hence in the presence of electric and magnetic field vector which vibrate perpendicular to each other and get perturbation EM waves travels in a vacuum.

The Magnetic field is produced by a moving charged particle. A force is exerted by this magnetic field on other moving particles. The force on these charges is always perpendicular to the direction of their velocity and therefore only changes the direction of the velocity, not the speed.

So, the electromagnetic field is produced by an accelerating charged particle. Electromagnetic waves are nothing but electric and magnetic fields traveling through free space with the speed of light.
