To design an electromagnet capable of lifting a 1 kg weight, key factors include the number of wire turns, the type of core material, and the voltage applied. The user seeks guidance on precise measurements and calculations for effective lift, emphasizing cost-effectiveness. Recommendations suggest using a ferromagnetic core to enhance magnetic field strength and experimenting with different wire gauges for optimal performance. The importance of calculating the required current and understanding the relationship between turns and lifting capacity is highlighted. Accurate design parameters are crucial for achieving the desired lifting capability.
