Tesla Field Meter 对比 Electromag 的使用情况和统计数据

This application measures the magnitude of the magnetic field. The Tesla Meter will respond to a static magnetic field as well as the magnetic field radiated through the application of alternating current. The research on the adverse biological effects in the presence of magnetic fields, whether static or alternating, is inconclusive, so it's best to practice prudent avoidance. Low level magnetic fields are naturally generated by the Earth. Higher level magnetic fields are generated from microwave ovens as well as the clock radio next to your bedside. Use this Tesla Meter to make a qualitative assessment of the strength of magnetic field exposure.

Electromag

Electromag is an educative application in support to a high-school or university course of electromagnetism. It contains not only a memorandum of the basic equations, but it also contains approximately twenty animations illustrating the various concepts of electromagnetism. This application runs also on iPad and iPod Touch 3rd generation and later. 50 screens of electromagnetism! For teachers !! Connect your iPad with a video projector and show the animations to your students in classroom. List of covered subjects: Electrostatics: Coulomb'sLaw, Electric Field, Gauss Theorem, Electric Potential, Capacitance. Electric Current: Current and Resistance, Circuits. Magnetism: Magnetic Field, Magnetic Fields Due to Currents, Electromagnetic Induction, Inductance. Electromagnetism: Maxwell Equations, Wave Equation. Physical Constants. Each section contains at least one animation of which some in 3D. List of animations: - Coulomb's law, - Electric field lines, - Movement of a charge in electric field, - Electric dipole, - Lead-acid battery, - Torque on a current loop (in 3D), - Charge in magnetic field, - Cyclotron, - Induction field due to a current in a long straight wire (in 3D), - Generator (in 3D).
