The Biot-Savart law
... Let’s consider an ideal solenoid (infinitely long and no space between the windings, for which field is zero outside the solenoid and of constant magnitude inside the solenoid). For a length of solenoid containing windings each carrying current , and for an “Amperian” rectangular loop that encloses ...

... We introduce concept called ‘ charge’ to describe electrical phenomenon. The simplest electrical phenomenon is electrostatic(deal with only static charge) problem. Before 19C, we recognized that electrical and magnetic phenomenon don’ t have any relation each other because what we could do is only d ...

... The increasing B field into the page must be countered by an induced flux out of the page. This can be accomplished by induced current in the counterclockwise direction in the wire loop. Example 3: A wire loop is being pulled through a uniform magnetic field that suddenly ends. What is the direction ...

... electrons are magnetically dilute, and so the unpaired electrons in one atom are not aligned with those in other atoms. However, in ferromagnetic materials, such as metallic iron, or iron oxides such as magnetite (Fe3O4), where the paramagnetic iron atoms are very close together, they can create an ...
