Mercury`s Weak Magnetic Field: Result of Magnetospheric Feedback?
... such a weak field may originate. A few models bypass the need for a conventional dynamo in a convective core, by invoking core-mantle boundary (CMB) topography [1] or crustal magnetization [2]. The confirmation that Mercury has a liquid outer core [3] has given support to the possibility of a dynamo ...

Chapter 29 Magnetic Fields Due to Currents
... due to the current in wire b, we would find that the force is directly toward wire b; hence Parallel currents attract each other, and antiparallel currents repel each other. The definition of ampere: the ampere is that constant current which, if maintained in two straight, parallel conductors of inf ...

Applied Magnetism
... • When an external magnetic field is applied to a material, these current loops will tend to align in such a way as to oppose the applied field. • This may be viewed as an atomic version of Lenz's law: induced magnetic fields tend to oppose the change which created them. Materials in which this effe ...

Experiment 10 Magnetic Fields and Induction
... Experimentally, we can measure the magnetic field of a macroscopic current with finite size, instead of an infinitesimal current element. Eq.(1) is therefore of theoretically significance only. To obtain the magnetic field of a current of finite size, it is necessary to integrate Eq.(1) over the tot ...
