How Can I Increase the Flux Density of My Electromagnet?

AI Thread Summary
To increase the flux density of an electromagnet beyond 1 tesla, consider using materials like plain old iron, which can achieve 1.5 to 2 tesla. High-performance permanent magnets, such as NdFeB, are also available and can exceed 1.5 tesla. The core saturation limits the magnetic field strength, so selecting the right core material is crucial. Additionally, optimizing the design and configuration of the electromagnet may help improve performance. Exploring these options can lead to a more effective electromagnet design.

Hi,

I am trying to design an electromagnet. I am utilising the lorentz force equation to develop the force. i.e. F= BIL.

The problem is I can't increase value of B beyond 1 tesla as the core saturates. Also high current is not feasible.

Can anyone suggest how to increase the value of flux density (B). Is there some other material present that can give flux density more than 1T.

Anticipating a positive reply.

Thanks is advance.

Plain old iron should go up to 1.5 to 2 tesla.
 
You don't say what it's for so I don't know if this is at all applicable but you can get NdFeB permanent magnets quite cheaply nowadays. They go up to over 1.5T.
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
