Quiz zum Vortrag
The strength of the magnetic field of a wire carrying current I at distance r from the wire has the following proportionality relation: B ∝ I/r, lets assume the proportionality constant is µ' so we get B = µ'I/r. What is the strength of the magnetic field of a long straight wire carrying current I = 2 A at a distance r = 1 m from the wire? (µ' = 2 ✕ 10⁻⁷ T.m/A)
- 4 ✕ 10⁻⁷ T
- 2 ✕ 10⁻⁷ T
- 2 T
- 4 T
- 1/2 ✕ 10⁻⁷ T
Two parallel long wires each carry a current of 2 A. The current flows in the same direction through the wires and the distance between the wires is 10 cm. What is the strength of the magnetic field in the middle, 5 cm apart from each wire? (B = µ'I/r , µ' = 2 ✕ 10⁻⁷ T.m/A)
- 0 T
- 8 ✕ 10⁻⁶ T
- 1.60✕ 10⁻⁵ T
- 4 ✕ 10⁻⁶ T
- 80 T
Two parallel long wires each carry a current of 2 A. The current flows in the opposite direction through the wires and the distance between the wires is 10 cm. What is the strength of the magnetic field in the middle, 5 cm apart from each wire? (B = µ'I/r , µ' = 2 ✕ 10⁻⁷ T.m/A)
- 1.6 ✕ 10⁻⁵ T
- 0 T
- 8 ✕ 10⁻⁶ T
- 4 ✕ 10⁻⁶ T
- 1.6 ✕ 10⁻⁷ T
