1. The magnetic field

2. Concept: the magnetic field
Permanent magnets always have two poles (South and North), demonstration of the presence of the magnetic field

4. Electromagnet

5. Common sense knowledge about the magnetic fields
- How compass is working?
- Forces between the permanent magnets: attraction and repulsion
Forces between magnets and certain metals (iron): always attraction
Between moving magnets and conductors (copper, aluminuim): repulsion

6. The magnetic field as a physical phenomenon
Magnetic induction vector, magnetic field vector, B-vector, magnitude and direction
Unit: 1Tesla, 1T

7. Picture of the magnetic field
Is chaning in the space

8. Picture of magnetic field: field lines
B is tangential to the field lines at any points.

9. Definition of
A magnetic field (sometimes) exerts a force to the moving charged particle. It depents on the direction of the field and the velocity.

11. Magnetic force is always perpendicular to the velocity of the charged particle.
 It is able to change the direction of the velocity ony, it is not able to change the speed.

14. Magnetic Field and electromagnetic force
Lorentz-formula for the electromagnetic force. Direction: Right hand rule

15. Magnetic force on the current-carrying wire
