Degree: Physics and Astronomy (Masters) - Durham University
Hi! My name is Jakub and I'm studying Physics and Astronomy at Durham University. I have been interested in sciences for as long as I can remeber and I really enjoy sharing that passion with others, be it through tutoring or a friendly conversation during lunch break. I have gained lots of experience teaching and helping my friends; now I try to incorporate these skills in the online environment.
The content and the structure of the sessions are entirely up to you! I am very flexible and can adjust my teaching to all learning styles. Recently, I have tutored both small and large groups (3-12 people) as well as provided individual lessons, which allowed me to re-evaluate and improve my teaching methods.
I always try to ensure my students really understand the concepts rather than only solve questions correctly. To do this, I provide various analogies and extra materials as well as check with you that you have fully grasped the given ideas, either in a conversation or through my own examples tailored to your needs. I often choose to use additional resources to offer you an alternative perspective on the problems, at the same time keeping track of the syllabus and past exam papers to make sure you get most of the session.
If you're interested...
If you think I'm the right tutor for you, please send me a message or arrange the free 'Meet the Tutor Session'. Please also specify which topics/questions you would like to cover so that I can prepare the necessary materials:)
Looking forward to hearing from you,

A typical transformer consists of an iron core with two coils wound around it - the primary and the secondary. Any current-carrying wire produces a magnetic field around it, but because the primary coil carries an alternating current, it's going to produce a changing magnetic field. The alternating magnetic flux from the primary coil is going to penetrate the secondary coil.
Now, let's recall the Faraday's Law:
'The magnitude of an induced e.m.f is proportional to the rate of change of flux linkage'.
Since the flux is alternating, its rate of change cannot be zero or even constant - it has to be alternating as well. Therefore, a changing e.m.f is going to produce an AC in the secondary coil (provided it is a part of a closed circuit).see more
