WebThe magnetic field at the center of the solenoid is measured to be 4. 9 × 1 0 T. Calculate the current in the wire. Give your answer in amperes to 2 decimal places. Use a value of 4 𝜋 × 1 0 T⋅m/A for 𝜇 . Answer Recall that the equation 𝐵 = 𝜇 𝑁 𝐼 𝐿 can be put into a form that relates the variables to current: 𝐼 = 𝐵 𝐿 𝜇 𝑁. WebThe magnetic field at a distance x from the centre of the loop along the axial line is given as: B= 2(x 2+R 2) 23μ 0IR 2 The magnetic induction at a point at a large distance d on the axial line of circular coil of small radius carrying current is 120 μT. At a distance 2d the magnetic induction would be: B= 2(a 2+x 2) 23μ 0⋅i⋅a 2 a<<

Web13 mrt. 2024 · The magnetic field generated due to the current-carrying circular conductor at its center is given as: ⇒ B = μ 0 i 2 r This result has been obtained from Biot Savarts Law. EXPLANATION: The Magnetic Field Produced due to the Semi-Circular wire is half of that of Circular wire. So, the magnetic field produced at the center of the wire Web7 apr. 2024 · This law is used to determine the strength of the magnetic field at any point due to a current-carrying conductor. Biot-savart’s law for the magnetic field obeys inverse square law and the superposition principle.
