A wire of length l carries a steady current. It is bent first to form a circular plane loop of one turn. The magnetic field at the centre of the loop is B. The same length is now bent more sharply to give a dou
An analytic expression has several advantages for determining the spatial distribution of the magnetic field in an efficient way. In this paper, an analytic approximation for the vector potential and the magnetic flux density of a filamentary circular current loop is proposed. The derivation of the ...
(A) : The magnetic field at the centre of a circular coil carrying current could be calculated using Amperes law. (R) : Biot savart law could be derived from Amperes law. View Solution Figure shows five lettered regions in which a uniform magnetic field extends directly either out of the...
How to find magnetic field between two parallel current-carrying wires? A 0.60-T magnetic field is directed perpendicular to the plane of a circular loop of radius 0.40 m. What is the magnitude of the magnetic flux through the loop?
Static magnetic field (SMF) promoting bone tissue remodeling is a potential non-invasive therapy technique to accelerate orthodontic tooth movement (OTM). The periodontal ligament stem cells (PDLSCs), which are mechanosensitive cells, are essential for force-induced bone remodeling and OTM. However, ...
at the centre of the circular loop, magnetic field lines become straight lines. At every point of a loop, the concentric circles representing the magnetic field around it would become larger and larger as we move away from the loop. The strength increases as we go closer to the centre of ...
Here, B0=ωB/α is the magnetic field at the centre of trap, ωB is the cyclotron frequency, α=q/m is the particle's charge-to-mass ratio and z0 the distance between coil and centre. Note that (28a), (28b), (28c) is not a valid approximation of a mirror trap's magnetic fiel...
the net magnetic field at the centre O is zero . Then the ratio of the currents in the loop and the straight conductor is View Solution Current I A flowing in a circular coil of radius r. then the magnetic induction at the centre is B. If the current is doubled then the magnetic ...

The projected area of the loop on the x−y plane is πρ2 with a new radius, ρ. Thus, the mean square of the radius can be written as 〈ρ2〉=〈x2〉 + 〈y2〉, which is the mean square of the distance of the orbiting electron normal to the magnetic field (z-axis) through...
