Problem 1: Find the value of the magnetic field inside a solenoid of 2 m and 100 turns per unit length if 5A of current is passing through it.įind the number of turns using the formula n = N/L. Sample Problems on Magnetic Field in a Solenoid Magnetism: quantities, units and relationships. Magnetic Field due to Solenoid and Toroid.Magnetic Field due to Current Carrying Conductor.Solenoids are used in various appliances and products, including computer printers and fuel injection gear in cars. Solenoids can be used to control valves electrically by applying mechanical force to the valve which can be used in door-locking systems to provide a secure closure.Electromagnets, Transformers, and Inductors are also applications of Solenoid which further has plenty of applications in real-world scenarios.What's the working volume where you want to achieve a certain field. For a short coil, maximum field strength is only achieved in the center point of the coil (r0, z 0). Before we discuss about suitable coil geometry, you should tell more clearly about the purpose of your design. Solenoids are used in various applications, including medical, locking systems, industrial use, automotive, and more. z is the distance from the coil center plane along the axis.Some of these applications are as follows: Applications of SolenoidĪs solenoids exhibit an immediate reaction when electricity is applied, making them useful in resolving various applications. This derives the formula for the magnetic field inside a solenoid. Role of Mahatma Gandhi in Freedom Struggle.
