Electric and magnetic fields are inextricably linked. In fact, as you will have learned in your particle physics topic they are carried by the same fundamental force, the electromagnetic force and its exchange boson, the photon.
There are some crucial rules and laws that you will learn about how the two fields behave and interact. It's crucial understanding to explain how generators work, how motors, and transformers work. You'll need to be fluent in applying Faraday's Law of electromagnetic induction, as well as able to explain how a Hall probe works and able to investigate magnetic flux.
We give magnetic flux density the symbol B, and so we call them B fields. There are some similarities and some differences between the three types of fields in A Level and they expect you to be able to use them and make comparisons between them. Get ready for another highly synoptic topic.

If customers can’t find it, it doesn’t exist. Clearly list and describe the services you offer. Also, be sure to showcase a premium service.
Having a big sale, on-site celebrity, or other event? Be sure to announce it so everybody knows and gets excited about it.
Are your customers raving about you on social media? Share their great stories to help turn potential customers into loyal ones.
Running a holiday sale or weekly special? Definitely promote it here to get customers excited about getting a sweet deal.
Have you opened a new location, redesigned your shop, or added a new product or service? Don't keep it to yourself, let folks know.
