I read in a book that Electromagnetic fields propagate at speed of light and carry energy and momentum.
Let's take electric field for example. Electric field is none other than a force per unit coulomb.So
1.How could a force(here field) move as force has no property of moving as force causes motion and it is the object which moves not the force?
2. How(Why) does a force carries energy because it is not something that contains energy?It is the matter that contains energy not the force.
3. If I am wrong and force contains energy than when oscillating magnetic field induces another electric field from where does the excess energy of electric field comes?
4. If an oscillating charge produces an EM wave then does the charge loses its kinetic energy?Does it means that if I "kick"(giving velocity) a charge at rest it is accelerated and radiates EM waves so does it comes to rest after radiating EM waves?
5. Are EM wave just a sort of magnitude waves that is fields don't propagate but it is the change in magnitude of field which propagates?
Please explain in good detail and don't expect me to understand higher level mathematics(hamiltonian etc) as I am just a High School Student.
Try to answer all of my question please these doubts are eating my brain off .
Thanks.
