How is an electric field created? What can produce magnetic fields? How do electricity and magnetism interact? What happens to charged particles in a magnetic field? How do scientists detect magnetic fields? Can the Earth's magnetic field be used to generate electricity?
State the nature of an α-particle.••■.[1](b)Describe how an electric field between two charged plates could be used to determine whether a beam of particles consists of α- or β-particles.[2](c)Describe the path of y-rays in a magnetic field.■.[1](d)State what is meant...
Static electricity or ESDis an electrical charge at rest. This is created by an imbalance of electrons that stay on a specific surface, or in the environmental air. The imbalance of electrons is caused by absence or surplus of electrons. This creates an electrical field that is capable of in...
How is the direction of an electric field defined? A field is not a vector, so it does not have a direction. The direction of the field is the direction of the force on a neutron. The direction of the field is the direction of the forc...
No. If they did, then the whole arrangement wouldn't be very useful. Right at the junction, however, they do mix and form a barrier, making it harder and harder for electrons on the N side to cross to the P side. Eventually, equilibrium is reached, and we have an electric field sep...

Science defines magnet as an object that is surrounded by a magnetic field and has the property, either natural or induced to attract. We have a magnetic field around us, and the ability to attract. That means we are magnets. And like magnets, we too we have both negative and positive ...
Finally, the strength of an electric field created by a point charge is equal to the Coulomb’s constant multiplied by the charge on the object generating the field, divided by the distance between this object and the test charge squared. ...
Electric Charge:As we told earlier that the number of electrons and number of protons are equal in a neutral body. The amount of negative charge and positive change is also equal in a neutral body since theelectric chargeof an electron and a proton is numerically equal but their polarity is...
I used the singleton design pattern to create a class of which there is always exactly one instance. The static reference ensures that one instance is created automatically by the time I first need to use it, and the private constructor ensures that no more instances can be erroneously created...
