What will be the magnetic field outside and inside a long current carrying solenoid?
What will be the magnetic field outside and inside a long current carrying solenoid? Outside the solenoid the magnetic field will be weak and the field lines will curl up to form closed loops. Hence, the magnetic field inside a solenoid carrying current will be the same at all the points. What is the value […]
How do you calculate half-life examples?
How do you calculate half-life examples? The quantity of radioactive nuclei at any given time will decrease to half as much in one half-life. For example, if there were 100g of Cf-251 in a sample at some time, after 800 years, there would be 50g of Cf-251 remaining. After another 800 years (1600 years total), […]
