List of top Physics Questions on Magnetic Field Due To A Current-Carrying Conductor

A long straight conductor carries a current of \(10\,\text{A}\). The magnetic field at a point \(20\,\text{cm}\) away from the conductor is \((\mu_0=4\pi\times10^{-7}\,\text{TmA}^{-1})\)

A long straight conductor carries a current of \(10\,\text{A}\). The magnetic field at a point \(20\,\text{cm}\) away from the conductor is \((\mu_0=4\pi\times10^{-7}\,\text{TmA}^{-1})\)

A steady current $I$ flow through a long straight wire of radius ‘$a$’. The current is uniformly distributed across its cross section. The ratio of the magnetic fields due to the wire at distance $\frac{a}{4}$ and $3a$ respectively from the axis of the wire is

Current $I$ is flowing in conductor shaped as shown in the figure. The radius of the curved part is $r$ and the length of straight portion is very large. The value of the magnetic field at the centre $O$ will be

A long solenoid has \(1000\) turns per meter and carries a current of \(2\,A\). The magnetic field inside the solenoid is: \[ (\mu_0 = 4\pi \times 10^{-7}\,TmA^{-1}) \]

Magnetic field \(|B|\) at a point \(P\) in the following network is:

There is a thin conducting wire carrying current. The value of magnetic field induction at any point on the conductor would be:
