Physik Magnet, Teltron Tube, Lorentz Force Klasse 11
The Magnet:
• Same magnetic poles repel
• Opposite magnetic poles attract
• Magnetic field lines go from magnetic north (red) to magnetic south (green)
• The magnetic field lines do not split or combine
• No magnetic monopole
Magnetic field (→)
𝑩
➔ B = ? (strength of the magnetic field)
Herleitung:
1. Electro motive force (e.m.f.) (Lorentzkraft FL/Fmagn)
2. Experiment:
FL ~ I → electric current
FL ~ l → length of the wire in the magnetic field
➔ FL = 𝑩 × 𝑰 × 𝒍 B = eine Konstante & mgnt. field
3. Defining B:
𝐹𝐿
B := 𝐼×𝑙
𝑁
[𝐵 ] = 1 = 1 T (Tesla)
𝐴×𝑚
