Question

in the case of electromagnetic field which of the following remains invariant under Lorentz transformation a) E*B b)B² c)E² d) H
​

Answer 1

E*B remains invariant under Lorentz transformation.

Explanation:

• In physics, E and B represent the electric and magnetic fields.
• The transformed components of E and B are represented as E' and B'.
• E and B are represented by 3- vectors in a three-dimensional phase.
• In inertial frames magnetic filed is represented s B' and electric field is E.
• Due to electric filed, a magnetic field in generated in a wire when the current flows through it.
