... 27-4 Force on an Electric Charge Moving in a Magnetic Field Conceptual Example 27-10: Velocity selector, or filter: crossed E and B fields. Some electronic devices and experiments need a beam of charged particles all moving at nearly the same velocity. This can be achieved using both a uniform elec ...

... Age of the Bacteria Prokaryotes dominated the Earth for most of its history. Multicellular eukaryotes are less than 1 billion years old. Prokaryotic fossils are very small, and consist mainly of fossilized cell walls. Some structures formed by mats of bacteria are found today and also fossilized fr ...

What is a Magnet?
... On the other hand, Components of the magnetic field in other directions are cancelled by opposing fields from neighbouring coils. Outside the solenoid the field is very weak due to this cancellation effect and for a solenoid which is long in comparison to its diameter, the field is very close to zer ...

... A fungus was growing and the bacterial colonies around it had been killed. Farther from the fungus, the bacteria looked normal. Excited by his observation, he showed the dish to an assistant, who remarked on how similar this seemed to Fleming’s famous discovery of lysozyme. Hoping he had discovered ...
